So you have the following equation:

A = 2πpw

When there are no space inbetween letters, that means they are being multiplied, so we can rewrite the equation like:

a = 2π × p × w

You know what A is, and what w is, so first substitute in the values:

A = 2π × p × w <em>(substitute in values for A and w)</em>

22 = 2π × p × 2 (<em>we want to get p by itself, so first divide both sides by 2, to get rid of the 2 that is next to the p)</em>

<em />

11 = 2π × p <em>(divide both sides by 2π, to get p all by itself)</em>

11 ÷ 2π = p

Now just type in [11 ÷ 2π] into a calculator to get what p is:

p = 11 ÷ 2π

p = 1.75 cm (rounded to 2 decimal places)
