How do you find a area with the diameter of a circle?

Answer 1

Area = Pi(radius)squared.

You only need the radius of a circle to find the area.

To find the radius, when you have the diameter, divide the diameter by 2, because the diameter forms two radii.

After you have found the radius, plug in the radius into the area equation:

Area = Pi(radius)squared

In other words, you can say the other equation for the area of a circle is:

Area = Pi(1/2Diameter)squared

Answer 2

divide it by 2 then multiply it by itself then multiply that by 3.14 (pie)

Answer 3

Area = 1/4 of (pi) x (diameter)2
