The area of a circle is 9π in². What is the circumference, in inches? Express your answer in terms of \piπ
dangina [55]

Answer:

6\pi in

Step-by-step explanation:

The formula to find the area of a circle: \pi r^{2}, where r is the radius.

The formula to find the circumference (perimeter) of a circle: 2\pi r, where r is the radius.

1) To find the circumference of the circle, we need to find the radius (r) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.

9\pi =\pi r^2

Cancel the \pi by bringing it to the other side.

9 =\pi r^2 ÷ \pi

9 = r^2\\\sqrt{9} = r\\3 = r

2) Find the circumference of the circle by using the formula, 2\pi r.

=  2*\pi *3

= 6\pi in
