Cylinder volume = pi* r^2 * h
Surface area = 2* pi*r^2 (top and bottom) + pi*2*r*h (side)
See the link for frustrum formula.
1.5 litres = 1500 cm^3. Pipe radius is 2.5cm, length is 100cm. pi*r^2*h = 1963 cm^3 or 1.96 litres
A equals radius, or 67.5 metres.
At 30 minutes, pi*t/B = 2*pi, OR 30/B = 2 OR B = 15
Sorry, I can't draw graphs on Yahoo. Hope I've helped a little.

entire circle ( one finished circle ) = 360 stages = 2? So ? is such as one hundred eighty stages to transform rad -> deg stages = X * one hundred eighty / ? the place X in rad. to transform deg -> rad rad = X * ?/one hundred eighty the place X in deg.
