Q:
# which of the following is the surface area of the right cylinder below a. 240pi^b. 540pi^c. 225pi^d. 252pi^

Accepted Solution

A:

The answer is 252 pi units.Explanation:The surface area of a right cylinder is [tex]2\pi rh+2\pi r^{2}[/tex]So, given height is = 15 unitsGiven radius is = 6 units.So, putting these values in the formula, we get:[tex](2\pi *6*15)+(2\pi (6)^{2} )[/tex]= [tex](2\pi *90)+(2\pi *36)[/tex]= [tex]180\pi +72\pi =252\pi[/tex] unitsHence, the answer is option D.
