Question

23) 6 in What is the surface area of this cylinder to the nearest integer? A) 57 in? B) 75 in? 132 in? D) 250 in?

Answer 1

`\text{Total Surface Area of a cylinder(TSA) = (2}*\pi* r* h)\text{ + (2}*\pi* r^2)`
`\begin{gathered} \pi=3.14 \\ h=\text{ 4in} \\ r=\text{ }(diameter)/(2)=(6)/(2)=\text{ 3 in} \end{gathered}`
`\begin{gathered} \text{TSA}=(2*3.14*3*4)\text{ + (2}*3.14*3^2) \\ \end{gathered}`
`\begin{gathered} \text{TSA}=\text{ }75.36+56.52 \\ \text{TSA}=131.88in^2 \\ TothenearestintergerTSA=132in^2 \end{gathered}`

Option C.......... answer
