M. barber uses 7/9 yard of wire for a ceiling fan. he uses 1/3 yard of wire to fix a light switch. how much more wire did he use for his ceiling fan than his light switch?

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!
