I need help! Please answer all!

1. 1/9 +2/9=

2. 1/5+2/5+2/5=

3. 5/6-2/6=

1/9 + 2/9 = 0.33

1/5+2/5+2/5= 1

5/6 - 2/6=0.5

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!
