The surface area of a sphere with a diameter of 12 units is:

A) 427.0 units squared.

B) 452.2 units squared.

C) 703.4 units squared.

D) 866.6 units squared

im pretty sure its B, but just need a confirmation

SA_{sphere} = 4 pi (radius)^2 = 4 pi (6)^2 = 4 pi (36) = 144 pi units^2 ≈

452.2 units^2

GOOD JOB !!!!
