6, if I get it wrong them I'm sorry
It is a scalene triangle as all the sides are unequal in length.
You just add up all the sides.
3.2 + 3.2 + 3.2 + 4.88 + 0.6
6.4 + 3.2 + 4.88 + 0.6
9.6 + 4.88 + 0.6
14.48 + 0.6
15.08
The perimeter is 15.08.
Hope this helps! :D
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
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
the full answer is 7234.56 (((4 * R)^2)

I am going to assume that 3 is supposed to be substituted for x so 3(3)+32= 41 members
