The equation to find a spheres surface area is 4 pi R ^2
and this works in any order
4 * 12 is 48 (4 * R)
48^2 is 2304 ((4 * R)^2)
the exact answer is 2304
the full answer is 7234.56 (((4 * R)^2)
)
Perimeter equals all sides added together so you would add all the numbers given together. For the side, without a number, you take the number above it and subtract 40.5 by 17.5 and that's your missing number. I think the answer is A. 143.1.
Hope this helps!
