Question

Determine the surface

Answer 1

In the given cylinder, radius = 2ft, height = 15 ft

The expression for the surface area of the cylinder is:

`\text{Surface Area = 2}\Pi rh+\text{ }\Pi r^2h`

Substitute the value and simplify:

`\begin{gathered} \text{Surface Area = 2}\Pi rh+\text{ 2}\Pi r^2 \\ \text{Surface Area = }2*(22)/(7)*2*15+2*(22)/(7)*2^2 \\ \text{Surface Area =}(1320)/(7)+(176)/(7) \\ \text{Surface Area =}(1496)/(7) \\ \text{Surface Area =}213.614ft^2 \\ \text{Surface Area =}213.6ft^2 \end{gathered}`

Answer: B) 213.6 ft²
