In a cylinder, radius = 7 and surface area
= 210 π. Find the height and volume of
the cylinder.
Answers
Answer: 1232
Step-by-step explanation:
Surface area = 210π
= 210*22/7
=660
therefore, total surface area of cylinder= 2πr(r + h)
660 = 2*22/7*7(7+h)
660 = 44(7+h)
660= 308+44h
660-308=44h
352=44h
352/44=h
8=h
Given, r=7 ,h=8
therefor , volume of cylinder = πr^2h
=22/7*7*7*8
= 22*7*8
=1232
