The trunk of a tree is cylindrical and its circumference is 176cm. If the length of the trunk is 3m. Find the volume of the timber that can be obtained from the trunk.

Text Solution

Verified by Experts

Circumference of cylindrical tank = `176cm`
Radius, `r`=circumference`/2pi`
`r=176/2pi`
`r=(176xx7)/(22xx2)`
`r=28cm`
`r=0.28m`
Length of trunk, `h=3m`
Volume, `V` = `pir^2h`
