Question

The circumference of a circle is 3π in.

What is the area of the circle?

1.5π in^2

2.25π in^2

6π in^2

9π in^2

Answer 1

2.25π in²

Explanation:

The area can be found from the circumference using the formula ...

A = C²/(4π)

Putting in the given dimension, you have ...

A = (3π)²/(4π) = (9/4)π = 2.25 π . . . . in²
