Question

The area of the base of a right circular cylinder is 154 cm² and its height is 8 centimetre find the curved surface area of the cylinder​

Answer 1

Answer:

πr^2= 154

solve it and put it in CSA formula

Answer 2

Answer:

Area of base = 154 cm^2

πr^2 = 154

r^2 = 154/π

r^2 = (154×7)/22

r^2 = 7 × 7

r = √7×7

r = 7 cm

height = 8cm ( given )

CSA of Cylinder = 2πrh

= 2 × 22/7 × 7 × 8

= 352 cm^2 Ans...
