Point C open parentheses 4 comma space 2 close parentheses divides the line segment joining points A open parentheses 2 comma space minus 1 close parentheses and B open parentheses x comma space y close parentheses such that A C : C B equal 3 : 1. What are the coordinates of point B?

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
