Question

The circumference of a circle is 6 inches. What is the area of the circle?

A. 3π in. squared
B.9π in squared
C.12π in. squared
D.36π in squared

​

Answer 1

Explanation:

2πr = 6, r = 3/π

πr² = π(3/π)² = 9/π in.²

Answer 2

(B) 9π in²

Explanation:

I’m going to assume that by 6 inches you meant 6π inches.

If the circumference of a circle is 6π inches, then it’s radius will be half of 6 (because the circumference of a circle is
`2\pi r`).

`6/2=3`

So the radius is 3.

Now that we know the radius, we can find the area by using the equation
`\pi r^2`.

`\pi 3^2\\\pi9\\9\pi`

Hope this helped!
