Answer:
The larger trampoline is larger in area by 75.36 feet²
Step-by-step explanation:
There are two trampolines here; the larger and the smaller one.
The trampoline's area can be found using the area of a circle which is πr² or πd²/4, where "r" and "d" represent radius and diameter respectively.
Here we will let D be <em>the diameter of the larger trampoline</em> and d should be taken as <em>the diameter of the smaller trampoline</em>.
So, the difference in area will be πD²/4 - πd²/4 = π/4 (D² - d²), where π is given as 3.14.
So, the area difference = × (14² - 10²) =
× (196 - 100) =
× (96) = 75.36 feet²
