The glass is 8 units. 2 units = 2.5 cm.  Multiply 8 by 2.5 and divide it by 2, and you get 10 cm

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
