Answer:
A = 576 π cm² or A ≈ 1808.64 cm²
Step-by-step explanation:
The equation for the surface area (A) of a sphere is:
A = 4 π r²
Since we know the radius (r) is 12, we can solve the equation:
A = 4 π 12²
A = 4 π 144
A = 576 π cm²
If you want to plug in 3.14 for pi, the solution is:
A = 576 (3.14)
A ≈ 1808.64 cm²
