Question:
The volume of a cylinder is \(πr^2h\). In the original cylinder, \(πr^2h = 128π\) so \(r^2(128π/8π) = 16\) and the radius, r, equals √16 = 4. In the new cylinder, the radius is doubled to 8 and the height is cut in half to 4. The resulting volume is \(π × 8^2 × 4 = 256πcm^3\).

Downloaded this app to improve my asvab score , and app actually gives me in detail how to solve and find the answer to the problems for math. Amazing.
