Surface area of the sphere = 4 *pi * r^2
= 4 * pi * (8)^2
= 4 * pi * 64
= 256pi
I hope that this answer has come to your help.
The standard deviation is 1, I believe...
You cannot solve this. TO solve both variables you need to have two equations. Please insert that equation in and I will solve this problem. :)
