Answer

a) $48\pi$ m b) 75.4 m

Work Step by Step

a) Use the formula for the circumference of a circle. $C=2\pi r$ Substitute the given radius for r. $C=2\pi(24)=48\pi$ b) Use the formula for the circumference of a circle. $C=\pi d$ Substitute the given diameter for d. $C=\pi(24)$ Use a calculator to find the circumference. $C=75.4$
