ANSWER
r = 0.94
EXPLANATION
The circumference of a circle of radius r is,
[tex]C=2\pi r[/tex]In this case, we know that the circumference is C = 5.9, and we have to find the radius. To do so, we have to solve the equation above for r, by dividing both sides by 2π,
[tex]\begin{gathered} \frac{2\pi r}{2\pi}=\frac{C}{2\pi} \\ \\ r=\frac{C}{2\pi} \end{gathered}[/tex]Replace the known values and solve,
[tex]r=\frac{5.9}{2\cdot\pi}\approx0.94[/tex]Hence, the radius is 0.94, rounded to the nearest hundredth.
