What is the volume of a hemisphere with a radius of 6.1 ft, rounded to the nearest tenth of a cubic foot?
The formula for the volume of a hemisphere is (2/3)πr³, where r is the radius of the hemisphere.
Plugging in the radius of 6.1 ft:
V = (2/3)π(6.1)³
V = (2/3)π(226.671)
V = (2/3)(711.897)
V = 474.598 cubic feet
Rounded to the nearest tenth:
V ≈ 474.6 cubic feet.
