Find the area of all shaded regions. Give your answer as a completely simplified exact value in terms of pi. (no approximations)

please mark me brainliest

hope this helps

Step-by-step explanation:

The shaded area will be the area of the larger circle minus the areas of the two smaller circles. The smaller circles are identical as they have the same radius length.

Therefore, we can create an equation:

⇒

⇒   [sub in values]

⇒   [simplify]

⇒   [collect like terms]

answer: idk

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
