Mathematics: Ismelda watches a soap bubble resting on a driveway. the bubble is in the shape of a hemisphere. when the bubble pops, the soap residue left behind is in the shape of a circle with the same diameter as the hemisphere. ismelda measures the diameter of the bubble as 6 inches. what volume of air was in the hemisphere before the bubble popped? (use 3.14 for π. round the answer to the nearest tenth, if necessary. recall that the formula for the volume of a sphere is .)

To get the volume of the sphere, let us use the formula V= $\frac{4}{3} \pi r^3$ . Since only the diameter is given, we are going to get the radius first using the formula r= $\frac{d}{2}$ .
r= $\frac{6}{2}$
r=3
Let us now find the volume.
V= $\frac{4}{3} \pi r^3$
V= $\frac{4}{3} (3.14)(3)^3$
V= $\frac{4}{3} (3.14)(27)$
V= $( \frac{4}{3} )(84.78)$
V= $\frac{4}{3} ( \frac{4239}{50} )$
V= $\frac{16956}{150}$
V=113.04

The volume of air is 113.04.
