What is the volume of a sphere with a radius of 9.1 ft, rounded to the nearest tenth of a cubic foot?
1 answer
The formula for the volume of a sphere is given by V = (4/3)πr^3, where r is the radius of the sphere. Plugging in the given value, we have V = (4/3)π(9.1^3) ≈ 3.1416 × (9.1 × 9.1 × 9.1) ≈ 3.1416 × 753.571 ≈ 2368.6756. Rounding to the nearest tenth, the volume is approximately 2368.7 cubic feet. Answer: \boxed{2368.7}.
