Volume of Spheres and Cones

Question 1 • Mathematical Models with Applications - MA4072 CR

Determine the volume of a sphere with a radius of 4.75 inches. Round your answer to the nearest hundredth. Use 3.14 for pi.

Answer
A
312.77 cu. in
B
237.48 cu. in
C
595.78 cu. in
D
448.69 cu. in

Explanation

Use the sphere volume formula, V = (4/3)πr³. With r = 4.75 inches and π = 3.14, V = (4/3)(3.14)(4.75³) ≈ 448.69 cubic inches. The correct choice is 448.69 cu. in.
