What is the volume of a hemisphere with a radius of 4.9 ft, rounded to the nearest tenth of a cubic foot?
The formula to calculate the volume of a hemisphere is V = (2/3)πr^3.
Plugging in the radius of 4.9 ft:
V = (2/3)π(4.9)^3
V ≈ (2/3)π(117.649)
V ≈ (2/3)(369.03)
V ≈ 246.02 cubic feet
Therefore, the volume of the hemisphere is approximately 246.0 cubic feet when rounded to the nearest tenth.
