Question

PLS ADD EXPLANATION
Cylinder radius is 2 cm height is 10cm what is the surface area

Answer 1

Given:

Radius of a cylinder = 2 cm

Height of the cylinder = 10 cm

To find:

The surface area of the cylinder.

Solution:

The total surface area of the cylinder is:

`A=2\pi rh+2\pi r^2`

Where, r is the radius and h is the height of the cylinder.

Putting
`r=2` and
`h=10` in the above formula, we get

`A=2\pi (2)(10)+2\pi (2)^2`

`A=40\pi +2\pi (4)`

`A=40\pi +8\pi`

`A=48\pi`

Therefore, the surface area of the cylinder is
`48\pi` square cm and its approximate value is 150.8 square cm.
