Question

find the curved surface area and the total surface area of a right circular cylinder whose height is 15 cm and the diameter of the cross section is 14 cm

Answer 1

Answer:660 cm^2 & 968 cm^2

Step-by-step explanation:We know,

CSA of cylinder =2×pi×r×h

=2×22/7×14/2×15

=660 cm^2

TSA of cylinder =2×pi×r (r+h)

=2×22/7×14/2 (14/2+15)

=44 (7+15)=44×22=968 cm^2
