Answer:
659.73
Step-by-step explanation:
i searched up surface area cylinder calculator to get the answer but incase u can't use that
A= 2(pi) r h + 2 (pi) r ^2
in this case it would be
A= 2 (pi) (7) (8) + 2(pi) 7^2
after that u should be able to get 659.73
if u didnt understand the explanation try searching up "surface area cylinder calculator" and it should pop up!
(my fault if the answer is wrong btw)
