Question

What is the surface area of the cylinder with height 3 ft and radius 3 ft ? Round your answer to the nearest thousand

Answer 1

Given the height (h) and the radius (r) of the cylinder:

`\begin{gathered} h=3ft \\ r=3ft \end{gathered}`

You can use the following formula for calculating the area of a cylinder:

`SA=2\pi rh+2\pi r^2`

Where "r" is the radius and "h" is the height of the cylinder.

Therefore, by substituting values into the formula and evaluating, you get:

`\begin{gathered} SA=2\pi(3ft)(3ft)+2\pi(3ft)^2 \\ SA\approx113.097ft^2 \end{gathered}`

Hence, the answer is: Second option.
