I NEED HELP ON 1 PLEASEEE

Step-by-step explanation:

Hi there!

From the given figure;

Radius(r) = 3 inch

Height (h) = 15 inch

Now;

Total surface area (TSA) = 2πr(r+h)

                              TSA = 2*()*3(3+15)

                               TSA = *18

                               TSA = 339.42in².

Therefore,  the answer is option c (339.29in²).

Hope it helps!
