The endpoints of the diameter of a circle are (-7, 3) and (5, 1). what is the center of the circle?

You need to find the MIDPOINT of the two points.
midpoint formula is ( (x1 + x2)/2, (y + y2)/2 ) The answer will be an ordered pair.
(-7 + 5)/2, (3 + 1)/2
(-2/2, 4/2)
(-1, 2)
The center of the circle is at (-1,2)

Hello!

the answer is:

the correct option is the option b.

why?

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!
