Don’t know what to do i mean i know what the main number is.

Step-by-step explanation:

128/2=64

64/2=32

32/2=16

16/2=8

8/2=4

4/2=2

2/2=1

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!

40% off the regular price is the correct answer.
