A cone with a diameter of 7.2 meters and slant height of 8.8 meters is being filled with water at a rate of 2.5 m^3 per minute. How many minutes will it take to fill the cone?

We need the perpendicular height, not the slant height

h^2 + 3.6^2 = 8.8^2

h^2 = 64.48

h= √64.48

Volume = π(3.6)^2 (√64.48)

time to fill = π(12.96)√64.48 /2.5 = appr 130.78 minutes
