Question

Find the lateral area for the cylinder with the given measurement. r = 4, h = 5

Answer 1

The lateral area for the cylinder with the given measurement is 125.6 unit²

Explanation:

Given : radius of cylinder = 4 units

Height of cylinder = 5 units

We have to find the lateral area for the cylinder with the given measurement.

Since, Lateral surface area of cylinder =
`2\pi rh`

Where r is radius of cylinder

and h is height of cylinder

Substitute, we have,

Lateral surface area of cylinder =
`2\pi (4)(5)`

Simplify, we have,

Lateral surface area of cylinder =
`40\pi`

Using π = 3.14

We have,

Lateral surface area of cylinder =
`40* 3.14=125.6`

Thus, the lateral area for the cylinder with the given measurement is 125.6 unit²

Answer 2

The answer is 125.6

The lateral area of a cylinder is:
LA = 2πrh

r = 4
h = 5
π = 3.14

LA = 2 * 3.14 * 4 * 5
LA = 125.6
