Question

write formula related to surface area and volume of cylinder and hollow cylinder

Answer 1

CSA( curved surface area)= 2πrh
surface area =2πr(r+h)
volume =πr²h

Answer 2

$volume \: of \: cylinder = \pi {r}^{2} h \\ voume \: of \: hollow \: cylinder = \pi( {r}^{2} - {r}^{2}) \\ \\ surface \: area \: of \: cylinder = 2\pi \: rh \\ \\ surfce \: area \: of \: hollow \: cylinder = 2\pi \: r(h - h)$
hope it helps
