The height of a cylinder with constant volume is inversely proportional to the square of its radius. If h = 8 cm when r = 4 cm, what is r when h = 2 cm?
1 Answer
see the explanation..
Explanation:
This is what the above statement says about the inverse relationship between HEIGHT and SQUARE OF RADIUS.
Now in next step when removing the proportional sign
{where k is constant (of volume)}
Putting the values of height and radius^2 we get;
Now we have calculated our constant value
Moving towards your question where radius is to be calculated.
Plugging the values into the equation:
Hence, for height of 2 cm with a constant of 128 we get the
