Question

a a solid right circular cylinder radius 14 c.m and height 8 c.m find tsa and csa​

Answer 1

Given that radius (r)=14cm Height(h)=8cm

T.s.a=2πr(r+h)

=2×22/7×14(14+8)

=2×44×22

=968×2

=1936..

c.s.a=2πrh

=2×22/7×14×8

=2×44×8

=88×8

=704

✏️✏️So,Total surface area of cylinder is1936 and the curved surface area is 704..✏️✏️
