Answer:

200π cm³ (in term of π)

628 cm³ (when define π = 3.14)

Step-by-step explanation:

Given:

Volume of Cylinder:

[tex]\displaystyle \large{V=\pi r^2h}[/tex]

If you notice, the volume of cylinder is area of circular base * height.

Input given information in the formula:

[tex]\displaystyle \large{V=\pi \cdot 5^2 \cdot 8}[/tex]

Evaluate:

[tex]\displaystyle \large{V=\pi \cdot 25 \cdot 8}\\\displaystyle \large{V=200 \pi}[/tex]

Since all measurements are in centimeters. Therefore, our unit is cm³ since we are finding volume which is three-dimensional.

Fact

However, you didn’t specific which π value/digit should we use so I’ll only put both solutions in where first being in term of π and second being 3.14.

Therefore, the volume is:

Answer:

600$ rent for 5 days,

around 185 miles a day, meaning you are paying 0.35$x85=29.75 extra a day.

adding up to 120 a day+29.75=149.75 a day.

149.75x5=748.75 for 5 days not including gas prices.

925/25=185 gallons of gas. 4 dollars per gallon, meaning that 185x4=740 extra dollars in gas

748.75+740=1488.75$ for the entire trip.

A right triangle with a 45 degree angle means the two short sides are the same, so y = 30

the hypotenuse is the length of the side x sqrt (2), so x =30sqrt(2)

answer: x = 30sqrt(2) and y = 30

The length of the rectangular table the carpenter builds given the scale is 110 feet

A scale drawing is a smaller version of a larger image. The scale drawing is usually reduced at a constant dimension

Length of the table = (11 x 7 1/2) ÷ 3/4

(11 x 15/2) x 4/3 = 660/6 = 110 feet

Answer:

13.85kg

Step-by-step explanation:

7 3/4=7.75

2 1/2=2.5

3 3/5=3.6

7.75+2.5+3.6

=13.85kg

Area = length x width

area of files = 30 x 20 = 600 square feet

area of unmoved field = 16 x 26 = 416 square feet

area that was mowed = 600 - 416 = 184 square feet

answer: 184 square feet

Answer:

184 ft

Step-by-step explanation:

so, for this, the key is the smaller dimentions on the inside, they are the area of the smaller inner rectangle (416 ft) and the bigger dimentions on the outside, are for the entire rectangle including the mowed area (600 ft), but you dont know the exact value of the mowed area, so you would simply subtract the areas (600-416=184) and that number, 184, is the area of the mowed area that you didnt know.

Surface area of a hemisphere would be best to estimate the amount of fabric necessary to make an umbrella.

A three-dimensional solid called a hemisphere is exactly half the size of a sphere.

To find the amount of fabric that is necessary to make the umbrella.

Since, the shape of umbrella is like hemisphere.

And to find the amount of fabric of umbrella would be equal to surface area of hemisphere.

Implies that,

Amount of fabric of umbrella = surface area of hemisphere.

Hence, option (D) is correct.

Step-by-step explanation:

15-9 to find a^2, 4 is b^2, and then pythagorean thereoum, a^2+b^2=c^2.

Answer:

Step-by-step explanation:

The base of the triangle used to solve for x (Pythagorean Theorem) is 15 - 9 = 7

The height of the right triangle is 4 so now you have enought to solve for x

Givens

a = 7

b = 4

c = x

Equation

x^2 = b^2 + a^2

Solution

x^2 = 7^2 + 4^2

x^2 = 49 + 16

x^2 = 65               Take the square root of both sides

√x^2 = √65

Answer x = √65

Answer:

109

Step-by-step explanation:

the sum of 37 and 72 is equal to x

proof:  

37+72 = 109

three angles of a triangle form 180 degree

to find the angle which is not given,

180 - 109  = 71

as you can see, angle with the measure 71 degree and angle x form a straight line, which means their sum is 180

so,

x = 180 - 71

x = 109

that means ,

=>    37+72 = x

=>    109 = 109            [ 37+72 = 109, x = 109]

hope this helps :)

Answer:

Step-by-step explanation:

Find the value of x in this triangle .

We know that sum of all the interior angles of triangle is equal to 180° . Then ,

Therefore , Angle y = 71° .

Now , We know that Angle 3 and Angle 4 is equal to 180° because they are Linear pair . So ,

Therefore , value of Angle x is 109° .

Answer:

 A. The student earned $18 for cleaning out his neighbor's garage.

Step-by-step explanation:

 Since it given that a student spend $18 for a haircut this week also means that she/he gave away $18 also known as -$18.

Thus, base on the given answer choices:

[A] is the only one that can make it positive.

Going through all answer choice:

A. The student earned $18 for cleaning out his neighbor's garage.

Earned = +

B. The student paid his little brother $18 for doing his chores.

Paid = -

C. The student purchased a gift for his mom for $18.

Purchased = -

D. The student gave $18 to a friend.​

Gave = -

Hence, Answer is A. The student earned $18 for cleaning out his neighbor's garage.

Answer:

A. The student earned $18 for cleaning out his neighbor's garage.

Step-by-step explanation:

Since given that A student spent $18 for a haircut this week and asking for Which event, when combined with the student spending $18, will result in the student having $0 remaining

Thus, we know that spending is negative because we are using it so it -18

Base on the given answer choice below we can infer that

earned = +

Paid = -

Purchased = -

Gave = -

The only way to make it back with a $0 is to add $18

Thus the answer is A. The student earned $18 for cleaning out his neighbor's garage.

Since AC = BC, we can say that this triangle is isoceles (at C)

In an isoceles triangle, the two angles that does not belong to the top angle (which in this case is C) is equal to each other.

Now, we can find the sum of the 2 missing angles : 180 - 52 = 128.
And since they are equal, we can find b : 128 : 2 = 64/
