Question

I NEED HELP ON 1 PLEASEEE

Answer 1

Answer:

C

Step-by-step explanation:

SA of a cylinder formula:

A=2πrh+2πr^2

A=2π(3)(15)+2π(3)^2

A=339.29in^2

Hope that helps

Answer 2

Answer:

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*($\frac{22}{7}$)*3(3+15)

                               TSA = $\frac{132}{7}$*18

                               TSA = 339.42in².

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

Hope it helps!
