Question

How much is the total area surface that needs covered?

Answer 1

The Solution:

Given:

Required:

To find the total surface area of the cylinder.

`TSA=2\pi rh+2\pi r^2=2\pi r(h+r)`

In this case:

`\begin{gathered} r=(12)/(2)=6ft \\ h=26ft \end{gathered}`

Substituting these values, we get:

`TSA=(2*\pi*6)(26+6)=1206.3716\approx1206.37ft^2`

Therefore, the correct answer is 1206.37 square feet.
