1 answer:
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 =
r = 5
5) The radius is 5 inches.
