Chapter 1.2, Problem 63HP

To determine

To choose: a geometric formula and explain how the order of operation applies.

Answer to Problem 63HP

The geometric formula is $2\pi rh+2\pi r^2$ .

Explanation of Solution

Choose the geometric formula for the surface area of a cylinder which is ,

  $2\pi rh+2\pi r^2$

Explanation:

First to square of the radius, then to do the multiplication of $2\pi rh$ and also the multiplication of $2\pi r^2$ . Then add these two numbers and get,

  $2\pi rh+2\pi r^2$

So, the geometric formula is $2\pi rh+2\pi r^2$ .
