Okay, here we have this:

4.C:

Considering the provided cylinder, we are going to calculate the requested total area, so we obtain the following:

Then we will substitute in the following formula for the total area of a cylinder:

A= 2πr(h+r)

Replacing:

A= 2πr(h+r)

A= 2(22/7)(10)(10+10)

A= 2(22/7)(10)(20)

A= 2(22/7)(200)

A= (22/7)(400)

A=8800/7

A≈1257.14 cm^2

Finally we obtain that the total surface area of the cylinder is 8800/7cm^2 that is approximately 1257.14 cm^2.
