Answer:
18πm
Step-by-step explanation:
The area is πr^, so to find just the radius, take the square root of 81.
This means the radius is 9, and because the formula for the circumference is 2πr, simply double it and multiply by π to get 18π.

To find the area of an irregular shape (in general)
⇒ is best to split it into different regular shapes
⇒ (in this case), let's split into a half-circle and a square
Area of the half-circle:
⇒ half the area of a circle ([tex]\pi r^2[/tex])
⇒ Area of half-circle = [tex]\frac{1}{2}\pi r^2[/tex]
r: length of radius ⇒ half of length of the diameter ⇒ 8.5m[tex]\pi[/tex] = 3.14Area of Half Circle = [tex]\frac{1}{2}\pi (8.5)^2 = 113.5m^2[/tex]

a
20 cm
The square has a height of 20 cm.
Work out the shaded area.
Give your answer in terms of t.
Answers
Shaded area = 21.46
Step-by-step explanation:
First find area of square,
Area = length × width
A = 20 × 20
A = 400 cm^2
Secondly, find area of circle
Area of circle = (π)r^2
A = (π)10^2
A = 100 π
Thirdly, find the area outside of the circle
Area of square - Area of circle
400cm^2 - 100π
= 85.84
lastly divide the answer by 4 to find the shaded area
85.84 ÷ 4
= 21.46
There are 8 hamburger buns in a package. which number of hamburger buns would fill a whole number of packages: 18, 32, 44, 56?
Answers
Answer:
32 and 56?
Step-by-step explanation:
32 and 56 are related to 8.
32=8x4
56=8x7
The number that would fill a whole number of packages of hamburger buns is 32 ad 56.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
18, 32, 44, 56
We need to find which number can be evenly divided by 8 because there are 8 hamburger buns in a package.
Now,
18 is not divisible by 8, because 8 x 2 = 16, and 18 is greater than 16.
32 is divisible by 8 because 8 x 4 = 32.
44 is not divisible by 8, because 8 x 5 = 40, and 44 is greater than 40.
56 is divisible by 8 because 8 x 7 = 56.
Therefore,
32 and 56 would fill a whole number of packages of hamburger buns.

15. A plane took off and rose at an angle of 8º with the horizontal ground. As the plane flies over a water tower, it has covered a distance from the take off point of 2000 feet. How far apart are the take off point and the water tower?
Answers
I wrote it all down so you can understand it better
The required distance between the take-off point and the water tower is 1980.1 feet.
Given that,
A plane took off and rose at an angle of 8º with the horizontal ground. As the plane flies over a water tower, it has covered a distance from the take-off point of 2000 feet.
To determine how far apart are the take-off point and the water tower.
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Here,
Now,
The distance flying over inclination is 2000 feet at an angle of 8° with horizontal.
Now,
Required horizontal distance = 2000 * cos 8°
= 1980.1 feet.
Thus, the required distance between the take-off point and the water tower is 1980.1 feet.

Answers
Question: calculate the measure of angle JKL, i.e. mJKM+mMKL
Answer:
78°
Step-by-step explanation:
angle JKM is a tangent-chord intersection angle and equals half of the intercepted arc KM of 76°. Thus
mJKM = 76/2 = 38°
angle MKL is an inscribed angle and equals half of the intercepted arc ML of 80°, Thus
mMKL = 80/2 = 40°.
Therefore angle JKL = 38°+40° = 78°.

Find the missing side lengths. Round decimals to the nearest tenth.
Answers
Answer:
x=13.9
Step-by-step explanation:
To find x we need an angle other than the right angle to use a trigonometric function. To do this we could either use Sine = Opposite/Hypotenuse or Cosine = Adjacent/Hypotenuse.
In this case i'll be using sine.
To find the angle that is above the right angle we need to use the inverse of Sine. Set up the equation
[tex] \sin^{ - 1} = \frac{22}{26} [/tex]
The answer to this is about 57.8. So now we have an angle to use to solve for x.
So now we set up the proportion
[tex] \frac{ \cos(57.8) }{1} = \frac{x}{26} [/tex]
Cross multiply.
x = 26×cos(57.8)
Put this in a calculator and x is about 13.9
