220 square centimetre, 660 sq.cm, 440sq.cm​

Answer 1

Answer:

Given: Radius=7cm,

Height=10cm

Total surface area=2πr(h+r)sq.units

=2×

×7(10+7)

=44×17=748sq.cm

Answer 2

Step-by-step explanation:

We know the formula of curved surface area of cylinder:

CSA of cylinder = 2 × Pie × R × h

CSA of cylinder = 2 × 22/7 × 7 × 10

CSA of cylinder = 440 cm^2
