Question

What is the volume of a cone with a height of 6 centimeters and a radius of 2 centimeters (use 3.14 for )?

25.12 cubic centimeters
24.12 cubic centimeters
25.24 cubic centimeters
24.00 cubic centimeters

Answer 1

cone volumes are: (1/3) (base area) (height)

Answer 2

volume of a cone = 1/3 volume of the cylinder.

so (3.14)(2^2)(6)(1/3)

= 25.12

Answer 3

6/3 = 2 right off the bat..

2 (pi 2^2) = 8 pi
