A sphere with a radius of 6 cm has the same volume as a cylinder with a height of 4.5 cm. What is the radius of the cylinder

kari74 [83]

$\frac{4}{3} \pi r^3= \pi r^2h \\
\frac{4}{3}6^3\pi= \pi r^2(4.5)\\
288\pi= \pi r^2(4.5)\\
\frac{288\pi}{4.5\pi}=r^2\\ 64 = r^2\\
 \sqrt{64} = \sqrt{r^2}\\ 8=r$
