Question

The circumference of a cirlcle is 6π inches. What is the area of the cirlce?

Answer 1

Answer:the answer would be A

Explanation:

C= 2πr

6π=2πr

——/—-

2π. 2π

3=r

A = 3π inches squared

Answer 2

The correct answer is B.

Start from the equation for the circumference and solve it for the radius:

`C = 2\pi r \implies r = (C)/(2\pi)`

So, the radius of the circumference is

`(6\pi)/(2\pi) = 3` inches

Once the radius in known, you can plug it in the formula for the area:

`A = \pir^2 = 9\pi` squared inches.
