Question

What is the exact circumference of a circle with a radius of 15 cm?

o 10 pi cm
o 15 pi cm
o 30 pi cm
o 60 pi cm

Answer 1

(C) 30πcm

Explanation:

In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.
