Question

What is the formula for calculating the area of a circle.

Answer 1

`A=\pi* r^2`

Explanation:

In order to find the area of a circle we multiply π by the radius, and to find the radius of a circle we have to look at the line that stops directly in the middle of the circle.


`\pi* r`

Once we then have the radius, we simply multiply the radius, (with an exponent of 2) by π and then we will have our answer. Of course, round if needed.

`A=\pi* r^2`

Hope this helps.
