What is the volume of a frustum with the radius of the top = .525cm, the radius of the bottom = .735cm and the height is 3.85?
:
The formula:
V = %28pi%2Ah%29%2F3 * %28R%5E2+%2B+Rr+%2B+r%5E2%29
:
In your frustum: r = .525; R = .735; h = 3.85
V = %28pi%2A3.85%29%2F3 * %28.735%5E2+%2B+%28.735%2A.525%29+%2B+.525%5E2%29
:
V = %2812.095%29%2F3 * %28.5402+%2B+.3859+%2B+.2756%29
:
V = 4.3167 * 1.2017
:
V = 5.187 cu cm

Check all this math on your own calculator, but this is the way you do it.
