Answer 1

Step-by-step explanation:

Total surface area = curved surface area + area of two circular plates.

Hence, the curved surface area of the cylinder is 220 cm2 and the total surface area of the cylinder is 377.14 cm2.

: In the place of π=227 we can also put π=3.14 into the formula and solve it as usual.
