V = 1649.34

Step-by-step explanation:

The formula for solving the volume of a right cylinder is V = pi r^2h where r = radius and h = height.

We know that radius is half the diameter so r = 5 because the diameter is 10 ft. We already know height = 21 so our equation looks like pi x 5^2 x 21

5^2 = 5 x 5= 25

so pi x 25 x 21 = 1649.34

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
