What is the volume of a hemisphere with a diameter of 4.4 ft, rounded to the nearest tenth of a cubic foot?

Answer 1

The volume of a hemisphere can be calculated using the formula V = (2/3)πr^3, where r is the radius of the hemisphere.

Given that the diameter is 4.4 ft, the radius is half of the diameter, so r = 4.4/2 = 2.2 ft.

Plugging this into the formula, we get:
V = (2/3)π(2.2)^3
V = (2/3)π(10.648)

V ≈ 22.315 cubic feet

Rounded to the nearest tenth, the volume of the hemisphere is 22.3 cubic feet.
