X+3y+5z=45
6x-3y+2z=-10
-2x+3y+8z=72

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!

a² + b²= c²

24² + 7² = c²

c= 25

the answer is a if my teacher taught me correct
