Below are sample questions representative of the exercises included on this worksheet and related 8.135 Volume of Spheres skill assessments:

Problem 1Difficulty: Hard
Four students found the volume of a sphere with radius 3.75 in using pi = 3.14. Who is correct to the nearest hundredth?
ACarlos, 58.88 in3
BNora, 1766.25 in3
CEmma, 235.50 in3
DLiam, 220.78 in3
Solution & Explanation:Use V = 4/3 x 3.14 x r3 with r = 3.75 in. The volume is 220.78125 in3, which rounds to 220.78 in3. So that student is correct.
Problem 2Difficulty: Hard
A sphere has diameter 17.5 cm. Four students wrote answers for its exact volume. Which student is correct?
AMalik, (42875/48)pi cm3
BOwen, (42875/16)pi cm3
CZoe, (42875/64)pi cm3
DRuby, (1225/3)pi cm3
Solution & Explanation:First find the radius: 17.5 / 2 = 8.75 cm. Then V = (42875/48)pi cm3. So the student who wrote (42875/48)pi cm3 is correct.
Problem 3Difficulty: Hard
Which sphere described below has a volume closest to 434.67 cm3 when pi = 3.14?
Adiameter 10 cm
Bdiameter 9.4 cm
Cradius 5.2 cm
Dradius 4.5 cm
Solution & Explanation:The target volume is 434.67 cm3. The sphere with diameter 9.4 cm gives that volume because its radius is 4.7 cm and V = 4/3 x 3.14 x r3.
