The numbers are not clustered around a common number. Two of the numbers are very large and one is very small.
A= 50.27 because the formula is pi times radius squared
C= 24.13 because the formula is 2 times pi times radius
Yes it is, and don't worry, I hate school too! Amazing username!
Using the distributive property, a(b+ c) = ab + ac. In this case, b is 30, so the blank is 30.
