Ответ:
375.795cm2
Step-by-step explanation:
To find the area of a cylinder, you'd use the formula:
2πr^2+2πrh
You can just plug in the numbers in this scenario in order to find your answer.
In this scenario, it would look like this:
(2 x 3.14 x 6.8 x 6.8)+ (2 x 3.14 x 6.8 x 2)
You'd then work out what is in each bracket:
(290.387)+(85.408)
Finally, you'd get the answer of 375.795cm2
Hope this helps!
