Answer : 16 feet

the area of a circle is 201.0624 square feet

The formula for area of the circle is
\pi r^2

Where r is the radius and value of π = 3.1416

Given area = 201.0624

Plug the values and find out radius 'r'

area of the circle =
\pi r^2

201.0624 =
3.1416*r^2

Divide by 3.1416 from both sides


64 = r^2

Take square root on both sides

r = 8

radius = 8 feet

Diameter = radius * 2= 8*2 = 16 feet

the diameter of the circle = 16 feet
