Ill give brainiest.
main show tank calculation:

the main show tank has a radius of 70 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. you must explain your answer using words, and you must show all work and calculations to receive credit.
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 35 feet and the height of tank #2 is 120 feet? you must explain your answer using words, and you must show all work and calculations to receive credit.
