We know that the surface area of the cylinder is:

Surface area = area of the bases + area of the sides

The area of the bases = 2* area of the circle

= 2* r^2 *pi

The area of the side = circumference of the circle * height...

We know that the surface area of the cylinder is:

Surface area = area of the bases + area of the sides

The area of the bases = 2* area of the circle

= 2* r^2 *pi

The area of the side = circumference of the circle * height of the cylinder

= 2*pi*r * h

Then the surface area is:

Surface area = 2r^2 * pi + h* 2*pi*r

Given r = 2 and h = 8

==> surface area = 2*(2^2)*pi + 8*2*pi*2

= 8pi + 32pi

= 40pi

= 125.66

**Then the surface area is : 125.66 cm^2**
