The volume is equal to the area of the base multiplied by the height. The height is 8 feet, and the base is 6 feet by 3 feet. To calculate the area of the base, you multiply the length of the two sides together. Therefore, the area of the base is 6x3, equal to 18. Then you multiply 18 by the height, 8, to get 144 cubic feet.
Step-by-step explanation: The formula to find the area of a circle is 3.14r^2. R stands for radius which is 6 in this case so just plug that in for R. 3.14(6)^2=113.1
