1.	A rectangular sheet of paper having length 28 cm and breadth 12 cm is folded along its breadth to form a cylinder. Find the curved surface area of the cylinder.
Answer» ong>Answer: length=28cm ,diameter =12CM So the RADIUS =diameter/2=6 Curved surface area of CYLINDER = $2\pi \: rh$ = $2 \times \frac{22}{7} \times 6 \times 28 \\ = 2 \times 22 \times 6 \times 4 \\ = 44 \times 24 = 1056 {cm}^{2}$

ong>Answer:

length=28cm ,diameter =12CM So the RADIUS =diameter/2=6

Curved surface area of CYLINDER =

$2\pi \: rh$

$2 \times \frac{22}{7} \times 6 \times 28 \\ = 2 \times 22 \times 6 \times 4 \\ = 44 \times 24 = 1056 {cm}^{2}$
