Answer to Question #6175 in Algebra for Ericka Muyrong
2. A cylindrical tank could hold 100.48m (raise to 3 ung m) of water. If the height of the tank is 2m, what is the radius of its base?
3. How many cubic meters of water a cylindrical tank can hold if its radius is 2m and its height is 3m?
V = H*2*pi*R,
so R = V / (2pi*H), so we need volume and height of cylinder
2. V = 100.48 m^3
R = V / (2pi*H) = 100.48 / (2 * 3.14 * 2) = 8 m
3. V = H*2*pi*R = 3 * 2 * 3.14 * 2 = 37.68 m^3
