Answer:
117.75, or Option C.
Step-by-step explanation:
Lateral Surface Area Formula:
[tex]Area = 2\pi rh[/tex]
Since we are given that the diameter is 5 inches, which converted to the radius is 2.5 (Diameter = 2 * Radius) and the height is 7.5 inches, we can insert that back into the formula, which gives us:
[tex]Area = 2\pi (2.5)(7.5)[/tex]
Then we simplify that to:
[tex]Area = 2\pi (18.75)[/tex]
If we also simplify π to be 3.14, and form out equation, which is:
[tex]Area = 2(3.14)(18.75)\\Area = 2(58.875)\\Area = 117.75[/tex]
Therefore, our final answer is 117.75, or Option C.
Hope this helped.
