6/9 is shaded and 67% is shaded

Step-by-step explanation:

6/9 is 66.66666666... which converted to a percentage (by multiplying by 100) makes 67%

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!
