2 to the 8th power of 256, and 8 to the 2nd power is 64. However, 8 to the third power is 512, which means that our answer has to be between 2 and 3. 8/3=2. Using an equation that works with all exponents of two (The exponenet that is right below the number we're looking for, or 2, in this case, plus ((number/exponent) will give us our answer. since 8/3 = 2, our answer will be 2+(2/3)
If you were making a replica ferris wheel it would be similar to the larger ferris wheel. This means that all the angles would be the same. If the angles were the same, the arc measures would also be the same.
