<PRE><B>Question 57029</B>
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 = {{{(pi*h)/3}}} * {{{(R^2 + Rr + r^2)}}}
:
In your frustum: r = .525; R = .735; h = 3.85
V = {{{(pi*3.85)/3}}} * {{{(.735^2 + (.735*.525) + .525^2)}}}
:
V = {{{(12.095)/3}}} * {{{(.5402 + .3859 + .2756)}}}
:
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.
