Please help

The area of the total circle (including the unshaded and shaded region)? = A

The area of the shaded region = (100/360) * A

Which formulas do you plan to use for these problems?

If show the work done with the formula - we can confirm whether it is correct.

What is \(\dfrac{100}{360}~?\) Why did I ask that?
