Question #3282

Assume you have a lawn that is 45 feet by 25 feet. Further, assume you buy a trampoline (a circular one) that is 15 feet in diameter. How much of the lawn is NOT under the tramp?

Expert's answer

The area of the trampoline is

π d2/4 = 255/4π = 63.75 π = 200.28 ft

The area of the lawn

45 * 25 = 1125 ft

1125-200.28 =

π d2/4 = 255/4π = 63.75 π = 200.28 ft

^{2}The area of the lawn

45 * 25 = 1125 ft

^{2}.1125-200.28 =

**924.72 ft**of the lawn is not under the trump.^{2}Need a fast expert's response?
