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
