Since the end (base) of a cylinder is a circle, the area of that circle is given by the formula:
area A=pi%2A+r%5E2
Multiplying by the height h we get volume:
V=pi%2A+r%5E2%2Ah
given:
a base diameter d=18in=> radius is r=9in
and a height of h=2in

then we have

V=3.14%2A+%289in%29%5E2%2A2in

V=3.14%2A+81in%5E2%2A2in

V=508.7in%5E3

The formula for the cylinder volume is known to anybody who is familiar with the word "cylinder".

What is the need to go to the forum with such a question ?


I see only one possible goal: to re-load to the tutors' shoulders the work which you MUST do on your own . . .
