How do you find the area of a circle?

???

A = 3.14r^2

Let say the radius(half of a circle) of a circle is 3feet.

You take 3.14 times the Radius (3feet) to the second power.

The radius (3feet) to the second power is 9. (3ft.x3ft.=9ft.)

9ft. x 3.14 is 28.26

The area of the circle is 28.26

Sounds hard but it isn't. just take half of the circle or radius and times it by its self and then times it by 3.14.

3 x 3 x 3.14 = 28.26

these answers are wrong ^
its: pie are squared

Sadprincess, what he said above IS pie are squared.

3.14r^2 = Pie are Squared

3.14 = Pie

R = Are

2^ = Squared
