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.
Diameter =14 cm
Radius =7 cm
Height =15 cm
So,
TSA of cylinder =2πr(r+h)
=2×227×7(7+15)
=2×227×7×22
=968 cm2
CSA of cylinder =2πrh
=2×227×7×15
=660 cm2
