Answer
The solutions are
a) $V(3,10) = 90\pi.$
b) $V(5,2) = 50\pi.$
c) $V(4,8) = 128\pi.$
d) $V(6,4) = 144\pi.$
Work Step by Step
We will substitute $r$ and $h$ from the first and the second coordinate from the given point into the function $V(r,h) = \pi r^2 h$.
a) $V(3,10) = \pi 3^2\times10= 90\pi.$
b) $V(5,2) = \pi 5^2\times 2 = 50\pi.$
c) $V(4,8) = \pi 4^2\times 8 = 128\pi.$
d) $V(6,4) = \pi 6^2\times 4 = 144\pi.$
