Answer:
47. 1 feet
Step-by-step explanation:
Brady is putting trim around the outside of the circular merry-go-round, so he needs to use the formula for circumference to find the amount of trim he needs to buy. The formula for the circumference of a circle is: C = dπ, where d = the measure of the diameter and π = 3.14. Using the given measure of the diameter:
C = 15(3.14) = 47.1 feet
