The area of a circle is 16 pi square feet. what is the radius

The formula for the area of a circle is pi*radius^2

16pi=pi*radius^2

Divide by pi

16=radius^2

Take the square root of both sides

Radius=4

The radius is 4 ft

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

16 pi = pi r^2

Divide each side by pi

16pi / pi = pi r^2/pi

16 = r^2

Take the square root of each side

sqrt (16) = sqrt (r^2)

4 = r
