Best Answer

First we have to find the radius:

pi*radius2 = 400*pi square meters

Divide both sides by pi and then square root both sides:

radius = 20 meters

2*pi*radius or pi*diameter = circumference

2*pi*20 = 40*pi meters

What is the radius and the area of a circle?

The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
