Question 4 • Foundations of Math 1
The diameter is twice the radius, so a radius of 16 inches gives a diameter of 2 × 16 = 32 inches. This makes the radius one-half the diameter, and the statement that the diameter is 32 inches is true. The sphere’s volume is (4/3)πr³ = (4/3)π(16³) = (16,384/3)π cubic inches, matching the stated volume in choice C.
