Question

The height of the right circular cylinder is bem and the radius of the base is 7 cm . Then the difference between the total suface avea and the curved surfacearea is​

Answer 1

Answer:

Radius of cylinder (r)=7cm

Height of cylinder (h)=15cm

Curved Surface Area =2πrh

=2×(22/7)×7×15

=660cm

2

Total Surface Area =2πr(h+r)

=2×(22/7)×7(15+7)

=2×22×22

=968cm
