Question

The radius and height of a cylinder are 5.6cm and 9cm respectively. Find the curved surface area and volume of cylinder.​

Answer 1

Step-by-step explanation:

We know that formula of the curved surface area of a cone is πrl, where r is the base radius and l is the slant height of the cone.

Here, given the base radius, r=5.6cm

slant height, l=9cm

∴ Curved surface area of the cone= πrl
