Question

Instructions: Find the surface area of each figure. Round your answers to the nearest tenth, if necessary. 10 mi. 4 mi. Surface Area: mi2

Answer 1

`\text{Surface Area of the Cylinder (A) = }2\pi r^2+2\pi rh\text{ = 2}\pi r(r+h)`
`\begin{gathered} \text{radius (r) =}4mi \\ \text{height (h) =}10mi \\ Therefore,\text{ A = 2}\pi(4)^2\text{ + 2}\pi(4)(10)\text{ }\mleft\lbrace\pi=3.142\mright\rbrace \\ A=100.544+251.36=351.904mi^2 \end{gathered}`

The final answer is

`351.9mi^2\text{ (to the nearest tenth)}`
