the answer to this question should be 1004.8 because first you need to use this formula to find the volume of a cylinder which is V=TTr^2h so remember the radius is half of the diameter.
So the half of 8 is 4 so 4 is the radius but remember that 4 is to the power of 2 in the exponent so the answer should be 16 because you multiplied 4 times 4 equals 16.
Then we need to multiplied 16 times 3.14 and 20 and when we do that we get an answer of 1,004.8 so 1004.8 feet^3 is the correct answer.
Step-by-step explanation: :DDDDD give brainliest to the first people that answer first than me if you want and have a great day.
