Question

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

Answer 1

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

Answer 2

Answer:

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

Step-by-step 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 = $40\times 3.14=125.6$

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