The area x the degrees of the angle / 360 degrees $$\left(\pi r^2\ \cdot\ \frac{\ \theta\ }{360\ \deg rees}\right)$$

The circumference x the degrees of the angle / 180 degrees $$\left(2\pi r\ \cdot\ \frac{\ \theta\ }{180\ \deg rees}\right)$$

The x the degrees of the angle / 180 degrees $$\left(\pi r^2\ \cdot\ \frac{\ \theta\ }{180\ \deg rees}\right)$$

The circumference x the degrees of the angle / 360 degrees $$\left(2\pi r\ \cdot\ \frac{\ \theta\ }{360\ \deg rees}\right)$$

The area * (degrees of the angle / 180 degrees) $$\pi r^2\cdot\left(\frac{\theta}{180\degree}\right)$$

The circumference * (degrees of the angle / 180 degrees) $$2\pi r^{ }\cdot\left(\frac{\theta}{180\degree}\right)$$

The area * (degrees of the angle / 360 degrees) $$\pi r^2\cdot\left(\frac{\theta}{360\degree}\right)$$

The circumference * (degrees of the angle / 360 degrees) $$2\pi r\cdot\left(\frac{\theta}{360\degree}\right)$$

I'll just do it in my head

Fractions, so I can cancel units on the top and bottom $$2\ dozen\ eggs\ \cdot\ \left(\frac{12\ eggs}{1\ dozen}\right)\ =\ 24\ eggs$$

Ratios with a colon separator

I don't need to show my work

Distance = rate / time

Distance = rate * time

Rate = Time / Distance

Distance = time / rate
