Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.

Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:

r= 10 ft

Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
= 2(π)(10)
= 20π ft
Answer:
center point: (-4, 2)
radius: 8 units
Step-by-step explanation:
To find the radius of a figure in a coordinate plane, you have to do x-y where x is the starting point and y is the ending point. so in this case:
-4-(-12)
= -4+12
= 8
Answer:
for the area of the Circle we use A=πd
A=3.14x12 A=37.68
for a rectangle it is A=ab
A=12x15 A=180
37.68+180=142.32
your answer is 142.32 m 2
