Chapter 11.5, Problem 6AR

To determine

To Find: The value of each expression using the given values of variables.

Answer to Problem 6AR

  $320\pi$

Explanation of Solution

Given: $2\pi r^2+2\pi rhwhenr=10,h=6$

Given: $r=10,h=6$

i.e.

  $\begin{array}{l}=2\pi r^2+2\pi rh\\ $ =2\pi {(10)}^2+2\pi (10)(6)$=200\pi +120\pi \\ =320\pi \end{array}$
