If the area of a circle measures 16π , what is the circumference of the circle in terms of π?

Answer 1

The area of a circle is given by the formula A = πr^2,
where r is the radius of the circle.

Given that the area of the circle is 16π, we have:

16π = πr^2
r^2 = 16
r = 4

The circumference of a circle is given by the formula C = 2πr.

Substituting the value of r = 4, we get:

C = 2π(4)
C = 8π

Therefore, the circumference of the circle is 8π.
