Answer:
πr + 2r
Step-by-step explanation:
Perimeter of Semicircle
The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.
Step-by-step explanation:
1. d = 22mm
circumference = πr + d
= 22/7 × 11 + 22
= 56.57 mm
2. r = 4 inches
circumference = πr + d
= 22/7 × 4 + 8
= 20.57 Inches
3. d = 10 yards
circumference = πr+d
= 22/7 × 5 + 10
= 25.71 yardsRelated Questions

Simplify using the rules of exponents:
b^4 x (b^2) ^6
A) b^12
B) b^48
C) b^16
D) b^68
Answers
Answer:
C
Step-by-step explanation:
Whenever you see a variable with an exponent (in parentheses) with another exponent (outside of the parentheses), you need to multiply them together.
[tex]2 \times 6 = 12[/tex]
Now that we only have b^4 x b^12, you might think we need to multiply the exponents again, but that would be wrong.
The only case where you should be multiplying exponents would be in the case of the first step.
Instead, we need to add them.
[tex] { b}^{4 + 12 = 16} [/tex]
Now we know our answer is C.

Answer: A. 9.4 units
Step-by-step explanation:
We could use the distance formula, but this problem asks us to use the Pythagorean theorem. This means we will "create" a right triangle and solve for the hypotenuse.
[1] First, we need to draw our triangle.
-> Please see attached.
[2] Now, we will count the length of the sides for the formula.
-> Please see attached.
[3] Lastly, we can use the Pythagorean theorem to solve for the missing side which also known as the hypotenuse. In this case, it is from point R to point S
a² + b² = c²

18 meters by 14 meters
Step-by-step explanation:
18 meters by 14 meters
Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).
This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:
2L+2W = 64
Now we know the area enclosed must be 252 so we have:
L* W = 252
Rewriting the second equation we get:
Plug this into first equation to get:
(multiply everything by L)
Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.
Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).
which is largest 3.3 times 10^5 or 3.1 times 10^5
Answers
Answer: 3.3 times 10^5 is bigger
Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.
so 100,000 multiplied by 3.3 = 330,000
or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.

she should put the sun 2.8 miles away
Step-by-step explanation:
had this question and got it right.
If we apply a rule of three
1 foot ----------------------- 2.389*10^5 miles
x --------------------------9.296*10^7 miles
x = ( 9.296*10^7 miles * 1 foot) / 2.389*10^5 miles

120*12=1440
He would have saved $1440.
To get 2/3 of $180, you’ll do
$60x2=$120 which is 2/3 of $180
Now, $120x12weeks= $1,440
Answer- Vincent will have $1,440 at the end of 12 weeks.
