i hope it helps this is not my paper.

Answer 2

✞︎ Given :-

• Height of the cylinder = 4 cm
• Radius of the cylinder = 7 cm

❦︎ To find :-

• The area of the cylinder .......?

✯︎ Solution :-

We know that ,

☯️ Curved Surface Area of cylinder = 2πrh

So, by substituting , we get

➪︎ $2 \times \frac{22}{7} \times 7 \times 4$

✰︎ C.S.A. of Cylinder is 176 cm ^2

And also ,

☯️ Total Surface Area = 2πr ( r + h )

So, by substituting , we get

➪︎ $2 \times \frac{22}{7} \times 7 \times (7 + 4)$

✰︎ T.S.A. of Cylinder is 484 cm ^2
