QuestionDetermine if the volume of sphere $Y$ (radius $2r$) is twice that of sphere $X$ (radius $r$) for $r=3$. a. True b. False

Studdy Solution
We can see that $\frac{32}{3}\pi r^3$ is not equal to $\frac{8}{3}\pi r^3$, so the volume of sphere $Y$ is not twice the volume of sphere $X$.
Therefore, the student's conjecture is false.
