A bit of experimentation at home persuades a cook that a wok holds about 3 L if it is 8 cm deep and the sphere has a y (mi) radius of 20 cm. To be sure, picture the wok as a solid of revolution, as shown in the gure, and calculate its volume with an integral. What is the real volume of the wok? (1 L: 1000 cm3) The volume of the wok is om3. (Round to the nearest cubic centimeter as needed.) Enter your answer in the answer box and then click Check
