Answer 2

The lateral surface area of cylinder is 31247.857 sq.cm.

Step-by-step explanation:

Circumference of circle = $2 \pi r$

We are given that The circumference of base of a right circular cylinder is 250 cm

So, $2 \pi r = 250\\2 \times \frac{22}{7} \times r = 250 \\r = \frac{250 \times 7}{2 \times 22}\\r=39.77$

Height of cylinder = 1.25 m 125 cm

Lateral surface area of cylinder = $2 \pi r h = 2 \times \frac{22}{7} \times 39.77 \times 125=31247.857 cm^2$

Hence The lateral surface area of cylinder is 31247.857 sq.cm.
