Question

What is the exact circumference of a circle with a radius of 15 cm? 10πcm 15πcm 30πcm 60πcm WIIL GIVE BRAINLIEST

Answer 1

Answer:

37 pi

Step-by-step explanation:

The circumference of a circle is equal to pi times the diameter.

The formula for the circumference of a circle is C=pi d,and since d = 37 ,we know that C=37 pi.

37 pi =116.238928183,but pi is irrational and the decimal will never end.

Thus,the most exact way to express the circumference is 37 pi.

Answer 2

Answer:

(C) 30πcm

Step-by-step 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.
