If an error of k % is made in measuring ...

If an error of `k %` is made in measuring the radius of a sphere, then percentage error in its volume.
k%
(b) 3k%
(c) 3k%
(d) `k/3%`

Text Solution

Verified by Experts

We know,Volume of sphere `V=4/3pi r^3`
`((dV)/(dr))=4pir^2`
Given, percentage error in measuring radius =k%
=`(Deltar)/r=k/100`
