Answer 1

Given:

Radius of the cylinder = 2 cm

Height of the cylinder = 3 cm

To find:

The surface area of the cylinder.

Solution:

The surface area of a cylinder is:

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

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

Putting $r=2,h=3,\pi = 3.14$, we get

$A=2(3.14)(2)(3)+2(3.14)(2)^2$

$A=37.68+25.12$

$A=62.8$

Therefore, the surface area of the cylinder is 62.8 square cm.
