Rearranging Equations Worksheet Answers. Dividing both sides of the equation by pi we get dfrac a pi textcolor blue r 2 now r is on its own on one side but it s not technically the subject since it is squared. Move h to the right side and divide it with 2ab a b m 2ab h a b the final answer is m 2ab h a b i given that i p r t 100.
If we now square root both sides of the equation and since r is always positive we get textcolor blue r sqrt dfrac a pi. Look at what you have but do not put any numbers in just yet. Move h to the right side and divide it with 2ab a b m 2ab h a b the final answer is m 2ab h a b i given that i p r t 100.
Look at what you have but do not put any numbers in just yet.
Move 100 to the left side and multiply it with i. Rearrange the equation so you place the intended variable on one side by itself. Dividing both sides of the equation by pi we get dfrac a pi textcolor blue r 2 now r is on its own on one side but it s not technically the subject since it is squared. These resources are designed to help students gain confidence with rearranging formulae and help them achieve the best grades possible.
