Question

Find the Lateral surface area of a cylinder whose radius is 14 cm and height is 5 cm. ​

Answer 1

439.82cm² is your answer

Answer 2

Given:

A cylinder with

• Radius = 14 cm
• Height = 5 cm

What To Do:

We have to find the lateral surface area of a cylinder.

Formula Used:

Lateral surface of cylinder = 2πrh

Solution:

Using the formula,

⇒ Lateral surface area = 2πrh

Substitute the values,

⇒ Lateral surface area = $\sf{2 \times \dfrac{22}{7} \times 14 \times 5}$

Cancel the 7 and 14,

⇒ Lateral surface area = 2 × 22 × 2 × 5

Multiply 2 and 22 and 2 and 5 seperately,

⇒ Lateral surface area = 44 × 10

Multiply 44 and 10,

⇒ Lateral surface area = 440 cm²

∴ Hence, the lateral surface of a cylinder is 440 cm².
