The radius of a sphere is `1.41` cm . its volume to an appropriate number of significant figure is

A

`11.73 cm^(3)`

B

`11.736 cm^(3)`

C

`11.7 cm^(3)`

D

`117 cm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
Radius of the sphere ,`r = 1.41 cm (3 "significant")` Volume of the sphere `V = (4)/(3) pi r^(3) = (4)/(3) xx 3.14 xx(1.41)^(3)`
`= 11.736cm^(3)`
Rounded off up to`3` significant) figure `= 11.7cm^(3)`
