The main tank has a radius of 70 feet. What is the volume of the quarter-sphere sized 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.

Answer 1

area/4= pi(r)^2/4
a/4=pi(40)^2/4
a/4=pi(1600)/4
area is about 5026.5/4
a/4=5026.5/4
a=1256.6
