Maths Question - Please Help...?

Man, π=3.14. That's in 2 decimal places. You can research the whole points but it doesn't really matter. C'mon it's on the calculator. And, is there a question or a drawing? You need to find the radius or the diameter. If you find the diameter, half it, it will give you the radius. So you need the radius for the formula of the sphere. Remember, r=radius. The formula is this: 4πr^2. Solve it for yourself, its easy. Goodluck. :)
