A special blend of coffee beans is going to be sold in cylindrical canisters whose dimensions always have a height that is two more inches than the radius. The table shows various volumes, V(r), for the given radii, r. Choose the function represented by the data. V(r) = 2πr2 V(r) = πr2 + 2r V(r) = πr3 + 2πr2 V(r) = πr3 + 2

If you are trying to move an attached term across the equal sign (=), what operation would you use to move it?

The radius of the earth is two times the radius of the moon. what fraction of the volume of the earth is the volume of the moon?
