The answer is 576π. Break down the formula: 4πr²=4*π*r(12)². 12² or 12*12 is 144. You still have 4 and π. So multiply 144 by the 4 to get 576 and finally multiply that by pi to get you the final answer of 576π.

Answer:

576π

Step-by-step explanation:

Surface Area of a Sphere

  • 4πr²

Given

  • r = 12

Solving

  • S.A. = 4 x π x (12)²
  • S.A. = 4 x 144 x π
  • S.A. = 576π
