Question 323657: how to find the volume of a cylinder if n=3.14,the radius is 6 inches and the height is 10 inches. (the units in the answer will be in cubic inches.) Answer by solver91311(24713) (Show Source):
The volume of a cylinder is the area of the base times the height. The area of the base is given by , so you can say the volume is:
For your problem:
is the EXACT answer.
Technically, , rather , therefore your volume, once you have done the arithmetic:
Furthermore, once you have calculated the approximation, you need to round off to the nearest whole cubic inch. You should never give the result of a computation involving measurements to a greater precision than the least precise given measurement. Both of your given measurements were to the nearest inch (there are no decimal places in the given measurements), hence the volume cannot properly be expressed to greater precision than the nearest whole cubic inch.
