Volume of a sphere
What is the volume of a hemisphere with a diameter of 45.7 m, rounded to the nearest tenth of a cubic meter?
The formula for the volume of a hemisphere is (2/3)πr^3, where r is the radius of the hemisphere.
Given that the diameter of the hemisphere is 45.7 m, the radius (r) can be calculated by dividing the diameter by 2:
r = 45.7 m / 2 = 22.85 m
Now, plug in the radius into the formula:
Volume = (2/3)π(22.85)^3
Volume ≈ 10219.5 cubic meters
Rounded to the nearest tenth of a cubic meter, the volume of the hemisphere is approximately 10219.5 cubic meters.
