Question

What is the area of a circle with a radius of 6 inches? (Leave your answer in terms of Pi. This means: do not multiple by 3.14, leave the pi symbol in its place)

Answer 1

36

Explanation:

Answer 2

`36\pi in^2`

Explanation:

1. The formula for the area of a circle is
`A=\pi r^2`

2. You are already given the radius. (r)

3. Plug the radius into the equation. You should get
`A=\pi (6)^2`

4. Leave in terms of pi, so (6)^2 is 36. (6x6)

5. This leaves you with
`36\pi in^2`

** units are important. Don't forget them (inches)
