1. main show tank calculation: the main show tank has a radius of 60 feet and forms a quarter sphere where the bottom of the pool is spherical and the top of the pool is flat. (imagine cutting a sphere in half vertically and then cutting it in half horizontally.) what is the volume of the quarter-sphere shaped tank? round your answer to the nearest whole number. 2. holding tank calculations: the holding tanks are congruent. each is in the shape of a cylinder that has been cut in half vertically. the bottom of each tank is a curved surface and the top of the pool is a flat surface. what is the volume of both tanks if the radius of tank #1 is 30 feet and the height of tank #2 is 110 feet? 3. the company is building a scale model of the theater’s main show tank for an investor's presentation. each dimension will be made ⅛ of the original dimension to accommodate the mock-up in the presentation room. what is the volume of the smaller mock-up tank? 4. using the information from #4, answer the following question by filling in the blank: the volume of the original main show tank is % of the mock-up of the tank.
