To find the radius of the cone, we can use the formula for the volume of a cone:
\[
V = \frac{1}{3} \pi r^2 h
\]
where \(V\) is the volume, \(r\) is the radius, and \(h\) is the height. Given that the volume \(V\) is 500 cm³ and the height \(h\) is 5 cm, we can substitute these values into the formula:
\[
500 = \frac{1}{3} \pi r^2 (5)
\]
Now, simplify the equation:
\[
500 = \frac{5}{3} \pi r^2
\]
To eliminate the fraction, multiply both sides by 3:
\[
1500 = 5 \pi r^2
\]
Now, divide both sides by \(5 \pi\):
\[
r^2 = \frac{1500}{5\pi}
\]
\[
r^2 = \frac{300}{\pi}
\]
Now, take the square root of both sides to find the radius \(r\):
\[
r = \sqrt{\frac{300}{\pi}}
\]
So, the radius of the cone can be calculated. However, you also asked about the statements given in the question. To find the equivalent cylinder, the volume of a cylinder is given by \(V = \pi r^2 h\). Given that the volume of the cone is 500 cm³ and the height is 5 cm, the radius of a cylinder with the same volume and height cannot be simplified directly.
To clarify the incorrect options:
- The radius of a cylinder with the same volume and height is not specified and cannot be calculated directly with the given information points.
- The option about the radius being the same with a volume \(500/3\) and same height does not make sense in the context.
The correct conclusion is that the radius of the cone can be calculated as discussed, which provides direct information rather than comparing it to the cylinder unless additional comparisons are specified with specific volumes.
