Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.

25)

arcQR=60°

26)

arcUWY=240°

27)

arcSU=112°

28)

arcSR=310°

hope it helps

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!
