Find the center and the radius of the circle given the equation of a circle below.

(x-2)^2 + (y-5)^2 = 49

a. Center: (2,5) & Radius=7

b. Center: (5,2) & Radius=49

c. Center: (-2,-5) & Radius=49

d. Center: (-5,-2) & Radius= 7

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!
