The volume of a cylinder is given by:
[tex]\begin{gathered} V=\pi r^2h \\ \end{gathered}[/tex]
Where:
V = Volume = 650cm³
r = Radius
h = Height = 10cm
Therefore, solve for r:
[tex]\begin{gathered} r^2=\frac{V}{\pi h} \\ r=\sqrt[]{\frac{V}{\pi h}} \\ r=\sqrt[]{\frac{650}{10\pi}} \\ r\approx4.5\operatorname{cm} \end{gathered}[/tex]
Answer:
r = 4.5cm
