Question

A cone has a diameter of 16 in. and a slant height of 17 in.

What is the approximate volume of the cone? Use 3.14 to approximate the value of straight pi. Round your answer to the nearest tenth, if necessary. (Hint: V equals 1 third straight pi r squared h )



A.
1004.8 in3

B.
1138.8 in3

C.
1259.3 in3

D.
4019.2 in3

Answer 1

radius = diameter / 2
radius = 16 / 2 = 8
Volume of the cone = 1/3 π r² h
= 1/3 * 3.14 * 8 * 8 * 17
= 1138.77
So volume of cone = 1138.77 in³ or 1138.8 in³

Correct Option is B.
