A Cone-shaped piece of paper has a height of 15 centimeters and a radius of 1.2 centimeters. The cone is 2/3 filled with sand. What is the approximate volume of the portion of the cone not filled with sand?
Answered by herp_derp
Volume of a Cone:
V = πr²h/3

Since 2/3 is filled with sand, 1/3 must not be filled with sand.

V = 1/3 [π(1.2 cm)²(15 cm)/3]
V = 7.54 cm³
