Circumference of the base of a cylindrical vessel is 154cm and its hight is 25cm . Find its curved surface area.

${ \huge{ \purple{Answer:}}}$

______________________________________

Circumference = 154 cm

2πr = 154

r = (154×7)/(2×22)

r = 49/2

r = 24.5 cm

Height (h) = 25 cm

Curved Surface Area = 2πrh

= 2×22/7×25×24.5

Curved Surface Area = 3850 cm²
