Answer:
i use slope calculators for these type of problems :)
Step-by-step explanation:
The volume formula of a cylinder is :

From the problem, the volume is 1 m^3 and the height is 0.6 m.
Substitute the given to the formula :

Take the square root of both sides of the equation :
![\begin{gathered} r^2=0.53 \\ r=\sqrt[]{0.53} \\ r=0.728 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20r%5E2%3D0.53%20%5C%5C%20r%3D%5Csqrt%5B%5D%7B0.53%7D%20%5C%5C%20r%3D0.728%20%5Cend%7Bgathered%7D)
The answer is r = 0.728 m
All I can say is that your equation is wrong
