  3. As soon as you enter the required input value(s), the Cylinder Curved Surface Area is calculated immediately, and displaed in the output section (present under input section).

Formula

To calculate the cylinder curved surface area, you can use the following formula.

\(A_c = \) \( 2 π r h \)

where

Calculation

Once you enter the input values in the calculator, the output parameters are calculated.

Examples

The following examples cover how to calcualte the Curved Surface Area when radius, and height are given.

1. What is the Curved Surface Area of Cylinder whose radius is 20 units, and height is 10 units?

Answer

Given:

  • radius, r = 20 units
  • height, h = 10 units

The formula to find the Curved Surface Area of a Cylinder is:

A_c = \( 2 π r h \)

Substitute given values in the above formula.

A_c = \( 2 \times 3.1415 \times20\times10\)

A_c = 1256.64 square units

∴ Curved Surface Area, A_c = 1256.64 square units

2. What is the Curved Surface Area of Cylinder whose radius is 1 units, and height is 0.5 units?

Answer

Given:

  • radius, r = 1 units
  • height, h = 0.5 units

The formula to find the Curved Surface Area of a Cylinder is:

A_c = \( 2 π r h \)

Substitute given values in the above formula.

A_c = \( 2 \times 3.1415 \times1\times0.5\)

A_c = 3.14 square units

∴ Curved Surface Area, A_c = 3.14 square units
