If the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π?

6π

Step-by-step explanation:

Area of a circle = πr².

To find the circumference, we have to find the radius first

Since the area of the circle in question is 9πcm²

9π = πr²

r² = 9π/π

r² = 9

r = +/-√9

= +/- 3.

To find the circumference now, we substitute for r in the formula above

Circumference = 2πr

= 2 x π x 3

= 6π.

Don't forget the π there must not be define

So the answer = 6π

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
