Electric power law: P = V x I   P = power in watts   Einstein's law: E â¦ = m x cÂ²   E = energy in joules, m = mass in kilograms, and c is the speed of light.
2. Know the formula for calculating the volume of a cone. The formula is V = 1/3Ïr 2 h, where r is the radius of the circular base of the cone, h is the height of the cone, and Ï is the constant pi, which can be rounded to 3.14. 1  The Ïr 2 part of the formula refers to the area of the circular base of the cone.
