What's the equation for the volume of the cylinder? Correct Answer: V (volume)= pi multiplied by R squared multiplied by the height Example: radius is 6" height is 30 V=3.1416•6•6•30 A drill draws a current (I) of 4.5 amps and resistance of 16.0 ohms, how do You find the power(watts)? Correct Answer: P=I squared (amps) multipled by R(resistance) Example:P=4.5•4.5•16.0 4.5•4.5=20.25 20.25•16.0=324 P=324 What is the equation for distance? Correct Answer: D=R•T D...
