If the volume of a cube is 4cm³, what is the radius of a circle and the height of a cone which has the same circle as its base ?!

Radius of circle = 0.7937...
The height of a cone can not be determined with the information provided.
To determine the radius of the circle, you must first know the dimensions of the cube. To determine the length of an edge of the cube, you use the formula for the volume of the cube. width x length x height. Since the width = length = height, then you know that your formula will be something like this:
4cm^3 = W x W x W
4cm^3 = W^3
to solve, you take the third root of 4. In other words 4^(1/3).
Now that you know 4^(1/3) = 1.5874 is the length, width, and height of the cube. Half of that would be the radius of your circle.
As for the height of the cone, you'd only be able to solve for that if you were given some additional information. It could be 1000 meters high or 1 mm high, you were given no constraints.
