The volume of a solid is described by the double integral 8/ ofv(64 - X12) 2 x y dydx If the order of the integral is reversed, find the lower limit of the inner integral. Note: 1. sqrt refers to square root, e.g. sqrt(3) means v(3). 2. A refers to power, e.g. 243 means 23. O -sqrt(64 - y12) O -8 O -64 0 0 o sqrt(64 - y12)
