Question

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

Answer 1

The correct answer is B.

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

$C = 2\pi r \implies r = \frac{C}{2\pi}$

So, the radius of the circumference is

$\frac{6\pi}{2\pi} = 3$ inches

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

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

Answer 2

Answer:the answer would be A

Step-by-step explanation:

C= 2πr

6π=2πr

——/—-

2π. 2π

3=r

A = 3π inches squared
