The volume formula of a cylinder is :
[tex]V=\pi r^2h[/tex]
From the problem, the volume is 1 m^3 and the height is 0.6 m.
Substitute the given to the formula :
[tex]\begin{gathered} 1=\pi r^2(0.6) \\ 1=3.14(0.6)r^2 \\ r^2=0.53 \end{gathered}[/tex]
Take the square root of both sides of the equation :
[tex]\begin{gathered} r^2=0.53 \\ r=\sqrt[]{0.53} \\ r=0.728 \end{gathered}[/tex]
The answer is r = 0.728 m
