What is the surface area of a cylinder with the given dimensions?

pogonyaev

Answer:

The surface area of a cylinder with the given dimensions is 571.48 $cm^2$ .

Step-by-step explanation:

To find the surface area, you need to use the formula $2\pi r^2 + h * 2\pi r$ where $r$ represents the radius and $h$ represents the height. In this problem, the expression would be $7^2 * 3.14 * 2 + 3.14*14*6$ = $49 * 6.28 + 3.14 * 84$ = $307.72+263.76$ = 571.48 $cm^2$ .
