Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations). AWARDING BRAINLIEST!!!

40π in²

Step-by-step explanation:

The area (A) of sector ODC is calculated as

A = area of circle × fraction of circle

   = πr² ×

   = π × 10² × = = 20π cm²

Sector OAB is congruent to sector ODC, thus

area of shaded regions = 2 × 20π = 40π in²

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
