Question

Find the radius of a circe given the area 25pi square inch.

Answer 1

Answer:

Radius = 5 inches

Step-by-step explanation:

1) We have to use the equation for the area of a circle to find the radius of the circle.

Area of a circle = πr^2

2) Plug in the information we already know, i.e., the area.

25π = πr^2

3) Cancel out the π on each side.

25 = r^2

4) Take the square root of 25

r = $\sqrt{25\\}$

r = 5

5) The radius is 5 inches.
