Volume of Spheres and Cones

Question 9 • Mathematical Models with Applications - MA4072 CR

Determine the volume of a sphere with a radius of 1.45 inches. Round your answer to the nearest hundredth. Use 3.14 for pi.

Answer
A
12.76 cu. in
B
7.48 cu. in
C
9.78 cu. in
D
10.98 cu. in

Explanation

Use the sphere volume formula, V = (4/3)πr³. With r = 1.45 and π = 3.14, V = (4/3)(3.14)(1.45³) ≈ 12.76 cubic inches. The correct choice is 12.76 cu. in.
