Answer:

Radius of cylinder (r)=7cm

Height of cylinder (h)=15cm

Curved Surface Area =2πrh

=2×(22/7)×7×15

=660cm

Total Surface Area =2πr(h+r)

=2×(22/7)×7(15+7)

=2×22×22

=968cm

Answer:

Csa of cylinder :2πrh= 2×3.14×8.4×15 =633cm square

TSA of cylinder = Csa of cylinder + πr×r= 633+3.14×8.4×8.4

=633-221.5 =411.5cm square

hope it helps :))
