Step-by-step explanation:
Using it's formula, it is found that the surface area of the mug that is painted blue is of 36.13 square inches.
<h3>What is the surface area of a cylinder?</h3>
The surface area of a cylinder of radius r and height h is given by:
![S = 2\pi r(r + h)](https://tex.z-dn.net/?f=S%20%3D%202%5Cpi%20r%28r%20%2B%20h%29)
Half of this area is inside the cylinder, and half is outside.
In this problem, the inside of the mug is blue, with r = 2 and h = 3.75, hence:
![S_b = \pi r(r + h) = 2\pi(2 + 3.75) = 36.13](https://tex.z-dn.net/?f=S_b%20%3D%20%5Cpi%20r%28r%20%2B%20h%29%20%3D%202%5Cpi%282%20%2B%203.75%29%20%3D%2036.13)
The surface area of the mug that is painted blue is of 36.13 square inches.
