Question 989330
They have provided the value of δr, which is 1. We also know that r = 5 and h = 11


We need to calculate dV/dr


Use calculus to differentiate V = pi*r^2*h with respect to r to get 


V = pi*r^2*h
dV/dr = 2*pi*r*h


Now plug in the given values


dV/dr = 2*pi*r*h
dV/dr = 2*pi*5*11
dV/dr = 110pi


So dV/dr ·δr is equal to 


dV/dr ·δr = 110pi*1 = 110pi


The approximate value of δV is 110pi
