Simply ,Square the radius, and then divide the radius squared into the tripled volume. For this example, the radius is 2. The square of 2 is 4, and 300 divided by 4 is 75. Divide the amount calculated in Step 2 by pi, which is an unending math constant that begins 3.14, to calculate the cone's height.
First combine like terms 6c + 14 = 4c + 4, then subtract 4c from both sides 2c + 14 = 4, then subtract 14 from both sides 2c = -10, then divide both sides by 2
