Question

A cone has a volume of 6 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

Select one:
a. 12 in3
b. 18 in3
c. 24 in3
d. 36 in3

Answer 1

B

Explanation:

Took the test

Answer 2

Formula for calculating volume of a cone is:

V = B*H/3

Formula for calculating volume of cylinder is:
V2 = B2*H2

because our cone fits exactly inside cylinder that means that their bases are the same and heights are the same. From this we can conclude (observing formulas for each volume) that cone has 3x less volume than our cylinder.

Cylinder volume is 6*3 = 18 in^3
