Question 887332: An orange has a diameter of 10 centimeters. How many square centimeters of peel will be removed before it can be eaten?
I know the formula for the surface area of a sphere is SA: 4x3.14xr2, I did all that, and my answer was 1.256, (yep, it was wrong)it turns out the answer was 314, it was SA: 4x3.14x5(to the second exponent) and it will give you 314, from where is that 5 to the second exponent coming from?? I'm really confused now.. thanks for the help!!!

Surface Area of a Sphere

SA = 4*pi*r^2

SA = 4*3.14*5^2 ... The radius is 10/2 = 5

SA = 314 square cm
