sorry if this is wrong, i'm new.

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3

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!
