Question

Find the curved surface area and total surface area of a right circular cylinder
whose height is 15 cm and the radius of the base is 7 cm​

Answer 1

Height=15cm

radius=7cm

Curved surface area of cylinder =2πr ×h

=2×22/7×7×15

=660cm^2

Total surface area of the cylinder ==2^rr (r+h)

=(44×22)cm^2

=968cm^2

Answer 2

Step-by-step explanation:

curved surface area of cylinder =2πrh

=2*22/7*7*15

=660sq cm

total surface area of cylinder =2πr(h+r)

2*22/7*7(15+7)

44*22=968 sq cm
