The circumference of a circle is equal to 72 pi. Find the radius of this circle
Answer provided by our tutors
The circumference of a circle is calculated by the formula C = 2*r*pi
C = 72 pi
2*r*pi = 72 pi divide both sides by pi
2*r = 72 divide both sides by 2
r = 72/2
r = 36
The radius of the circle is 36.
