Answer 1

Answer:

Step-by-step explanation:

Answer 2

The lateral surface area of cylinder is 864.29 sq.m.

Step-by-step explanation:

Length of sheet = 35 cm

Breadth of sheet = 25 cm

We are given that A rectangular sheet is rolled along the length to form a cylinder.

So, $2 \pi r = 35$

$2 \times \frac{22}{7} \times r = 35$

$r = \frac{35 \times 7}{2 \times 22}$

r=5.5

So Height of cylinder = 25 cm

Lateral surface area of cylinder = $2 \pi rh = 2 \times \frac{22}{7} \times 5.5 \times 25=864.28 cm^2$

Hence The lateral surface area of cylinder is 864.29 sq.m.
