Question

If curved surface area of cylinder is 1540 sq. cm and radius of the base is 7 cm then find volume of the cylinder. *​

Answer 1

Answer:

The radius of cylinder is r=7 cm

Curved surface area of right circular cylinder is 440 cm².

CSA=2\pi rhCSA=2πrh

440=2\times \frac{22}{7}\times 7\times h440=2×

The height is 10 cm.

The volume of the cylinder is V=\pi r^2 hV=πr
