Question

What is the area of a circle with a diameter of 6x? (Use 3.14 for R

Answer 1

The area of a circle is defined as Pi R^2

Since we only have the diameter and Pi, we need to solve for the radius.

The radius is 1/2 of the diameter, so divide 6 by 2 to get our radius.
6 / 2 = 3

Our radius is 3.

Now let's plug in our formula.

A = 3.14 x 3^2

3 x 3 = 9
9 x 3.14 = 28.26

Your area is 28.26 units ^2

I hope this helps!
