Answer:
Volume is 431288166770775 cubic feet.
Step-by-step explanation:
The height of the cylinder = 2214 ft
Let d be the diameter . Hence, we have
d = 225 × 2214 = 498150 ft
Hence, the radius should be half of diameter.

The volume of cylinder is given by

60= n/3 + 52
-52. -52
8= n/3
You then take 3/1 times 8 therefore you leave n by itself
n = 24
