Each piece has a radius of mm. Package 2 has pieces of gum shaped like spheres. Each piece has a radius of mm. Which package should the teenager buy? Round to the nearest millimeter.
- Find the volume of a piece of gum in package 1 by using the volume formula for a sphere.
- Multiply the volume of the single piece of gum in package 1 by to get the total volume of the gum in the package.
- The radius of each piece of gum in package 2 is mm. Find the volume of a piece of gum in package 2 by using the volume formula for a sphere.
- Multiply the volume of a single piece of gum in package 2 by to get the total volume of gum in the package.
- Compare the volumes of the two packages to determine the best purchase.
