The area of a circle is 9pi square meters. What is the circumference?

circumference of a circle=2πr

area=πr²

1) we calculate the radius of this circle.

dа ta:

area=9π m²

area=πr²

9π m²=πr²

r²=9π m² / π

r²=9 m²

r=√ (9 m²) = 3 m

2) we calculate the circumference:

circumference=2πr=2π (3 m) = 6π m

Answer: the circumference is 6π m
