HELP ME PLEASE LOVE THOU <3

12345 [234]

Answer:

$100\pi$

Step-by-step explanation:

Total Surface Area of cylinder = Lateral Surface Area + Area of both circle bases.

Lateral Surface Area = Circumference of Circle $\times$ Height

Lateral Surface Area = $(\pi \times2\times5) \times 5=50\pi$

Area of one circle base: $\pi (5)^{2} =25\pi$

Area of both circle bases: $25\pi \times2=50\pi$

Total Surface Area = $50\pi +50\pi =100\pi$
