The area of a circle is 25pi. what is the circumfrerence in terms of pi?

Hello!

Given that the area of a circle is found by using the formula: A = πr². Also, the circumference of a circle is: C = 2πr.

In order to find the circumference, we need to find the radius first. We can substitute the area into the area formula and solve for r.

25π = πr² (divide both sides by π)

25 = r² (take the square root of both sides)

r = 5

The radius of this circle is 5 units. With the radius, we can find the circumference.

C = 2π(5)

C = 10π, which is equal to about 31.4 units.

Therefore, the circumference of the circle is 10π units.

good luck on your studies! : )

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
