This proof was known to ancient greeks and does not involve calculus or integration. Take a hemisphere. Surround it by a cylinder of the same radius as the ...
that's the volume of the hollow center plus the filled shell, i.e. it is the total volume of the larger sphere. your formula is therefore V2 = 2 * V1. this becomes: 4/3 * pi * 20^3 = 2 * 4/3 * pi * r^3. r is the radius of V1. if you divide both sides of the equation by (2 * 4/3 * pi), you get: 20^3 / 2 = r^3 since 20^3 = 8000, then you get: r^3 ...

A square pyramid has a volume of 560 in^3, a base length of 10 in, and a height of 14 in. What is its base width? Answer by Earlsdon(6294) (Show Source):
Question 1165499: The formula for the volume V of a cylinder is V = πr2h, where r is the radius of the base and h is the height of the cylinder. Solve the formula for h. Choose the correct formula. A. h=Vπr2 B. h=Vπ/r2 C. h=Vr2/π D. h=V/πr2 Part B Find the height of a cylinder with a volume of 36π cm3 and a base with a radius of 3 cm. h ...
volume = (cross-sectional area)*(length) so, for your trapezium, its volume is given by area*length. area of trapezium = (h/2)(a+b), where a and b are the 2 parallel sides and h is the perpendicular distance between them.
