Find the circumference of a circle whose area is 60 pi cm^2

The circumference of the circle is 15.49π cm

Step-by-step explanation:

To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius

a = area = 60π

r = radius

a = π * r²

r = √(a/π)

r =  √(60π/π)

r = √60

r = 7.746 cm

now we use the formula to calculate the circumference of a circle

c = π * 2r

c = π * 2 * 7.746

c = 15.49π cm

The circumference of the circle is 15.49π cm

answer: c. is your answer
