86 and 87 utilize the Pythagorean theorem. Where those tangent lines meet the circle forms a right angle. So you have a side length of 6 and a hypotenuse of 22. So the missing side length is 21.16. For 87, its the same thing, but you have the 2 legs but are missing the hypotenuse.
Answer:
A
Step-by-step explanation:
we need to subtract half of the area of the circle from the area of the square to get the area of the shape on the picture.
Therefore a²-πb²/2 is the correct answer
