In order to solve this problem you will need to know the area of the circle 0.75_in in diameter which is calculated as follows: 0.75_in X pi (pi=3.1416) which is approximately equal to 2.3_in

follows, in this case I will not provide the conversion factor for converting from 1_in

^{2}then multiply this answer by the no. Of inches in 47_ft: To convert 47_ft to inches multiply 47_ft by 12_in/1_ft=547_inches to calculate the ttl volume in inches multiply 547_in x 2.3_in^{2}=1258_in^{3}now we convert 1258_in^{3}to gallons which is asfollows, in this case I will not provide the conversion factor for converting from 1_in

^{3}to gallons I will provide only the answer which is approx. 5.4_gallons.
