A cylinder, radius 1.325" and length 1" has what volume?

Question

A second cylinder has a radius of 2.75" and a length of 1" has what volume?

How much greater in volume is cyl.2 than cyl.1 ?

Answer 1

No wonder many kids are leaving school semi-literate and semi-numerate.

This is basic mathematics and the formula may be found in virtually any elementary textbook on mathematics.

The 'Volume of a cylinder' should not be beyond your capabilities given that you are able to use a computer.

Try doing some basic research.

Answer 2

Volume=area Xhight Area=3.14*(30)^2=2826 CM^2 Volume=2826*120=339120 CM^3 Volume=339120/1000=339.120 litre.

Answer 3

The volume of a cylinder is calculated by multiplying the cross sectional area by the height.
so pi times radius squared times height.
so the difference in volumes is:
pi x (2.75)squared x 1 - pi x (1.325) squared x1
which is the same as
pi x ((2.75)squared - (1.325) squared)
which is
pi x ((11/4)squared - (11/8) squared)
pi x ((22/8 x 22/8 - 11/8 x 11/8)
pi x ((22x22/8x8 -11x11/8x8))
pi x ((22x22- 11x11)/8x8)
pi x (484 - 121)/64
pi x (363/64)
22/7 x 363/64
22x363/(7x64)
7986/488
which is 17 cubic inches rounded to the nearest one.
Done by good old fashioned long arithmetic.

Answer 4

First cylinder = 3.14 * 1.325^2 * 1 =
Second cylinder = 3.14 * 2.75^2 * 1 =

Then subtract.
