Question

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

Answer 1

Answer:

Given that

Diameter of cylinder=14cm

Radius of cylinder =7cm

Height of cylinder =15cm

So,TSA of cylinder =2×22/7×r (r+h)

=2×22/7×7 (7+1=2×22/7×7×22

=968cm^2

CSA of cylinder=2×22/7×r×h

=2×22/7×7×15

=660cm^2
