Question

The volume of a right circular cylinder is 4620 cm3 and its base radius is 14cm. The curved surface area of the cylinder is ::

Answer 1

Answer:

The Volume of right circular cylinder = 4620cm³

Base of cylinder = 14cm

Radius of cylinder = 14cm

Curved surface area of cylinder = 2πrh

= 2×22/7×14×14

= 2×22×2×14

= 1232cm²

Answer 2

The curved surface area of the cylinder is 1980 cm².

Given,

The volume of a right circular cylinder = 4620 cm³.

The base radius of the cylinder is 14 cm.

To Find,

The curved surface area of the cylinder.

Solution,

The formula for calculating the volume of a right circular cone is

Volume = 1/3πr²h

So,

4620 = 1/3π(14)²h

h = 4620*3/196π

h = 13860/196π

The curved surface area of the cylinder is 2πrh

Curved surface area = 2π*14*13860/196π

Curved surface area = 1980 cm²

Hence, the curved surface area of the cylinder is 1980 cm².
