Question

the total surface area of a cylinder of radius 7cm is880cm2 Find the height and the volume of the cylinder​

Answer 1

Answer:

Height = 20 cm, Volume = 3080 cubic cm

Step-by-step explanation:

Total surface area of a cylinder = 2πr(h+r) = 880 square cm

now, r = 7 cm (given)

Therefore, h = 20 cm.

The Volume of a cylinder = πr²h

                                    = (22/7)(49)(20)

                                     = 3080 cubic cm.
