Step-by-step explanation:
diameter = 14
therefore radius = 7. i.e. diameter/2
Now,
TSA(total surface area) of the cylinder = 660 ..given.
TSA of cylinder = 2πr(h+r)
therefore, 660 = 2π r (h +r)
(we don't know the height)
660 = 2×(22/7)×7(h+7)
therefore, 660 = 44h+ 308
therefore,660-352 = 44h
therefore, 248 = 44h
therefore, h = 8cm
volume = πr²h
= (22/7)*7²*8
= 1232cm³
