Volume of cylinder
[tex]\pi {r}^{2} h[/tex]
Volume of the can = 300
[tex]300 = \pi {r}^{2} h[/tex]
[tex]300 = \frac{22}{7} {r}^{2} h[/tex]
[tex]300 \times \frac{7}{22} = {r}^{2} h[/tex]
[tex]150 \times \frac{7}{11} = {r}^{2} h[/tex]
[tex]95.45 = { r}^{2} h[/tex]
[tex] \frac{95.45}{h} = {r}^{2} [/tex]
[tex] \sqrt{ \frac{95.45}{h} } = r[/tex]
[tex] \frac{ \sqrt{95.45} }{ \sqrt{h} } = r[/tex]
