The length and the radius of a cylinder measured with a slide cllipers re found to be 4.54 cm and 1.75 cm respectively. Calculate the volume of the cylinder.

Answer

C, D

Explanation

Given that, for the cylinder
length`= l= 4.54 cm
radius
r=1.75 cm Volume= pir^2l
=(pi)x(4.54)xx(1.75)^2

since the minimum number of significant digits on a particular terms is 3, the result should have 3 significant digits and others should be rounded off. `:. Volume, V=pi r^2l
=(3.14)xx(1.75)xx(1.75)xx(4.54)
=43.6577 cm^3`
Since, it is to be rounded off to 3 significant digits
`V=43.7cm^3`
