Start with te formula for the volume of a cone:
V%5Bc%5D+=+%281%2F3%29%28pi%29r%5E2%2Ah Substitute: r = 6ft., h = 10ft. and pi+=+3.14 approx.
V%5Bc%5D+=+%281%2F3%29%283.14%29%286%5E2%29%2810%29
V%5Bc%5D+=+376.8cu.ft.
Since 1 cu.ft = 7.480510 gallons of water, then the capacity, C, is...
C+=+%28376.8%29%2A%287.480510%29
C+=+2818.656Gallons. Rounded to the nearest hundredth, this is:
highlight%28C+=+2818.66%29Gallons.
