I Do not know what to do
ANYONE help
plz

Answer 1

for circle in circle: 75π

circle in square: 64-16π

note that answers are in exact form, since I don't know how the answer should be written (exact or decimal etc.)

Explanation:

for circle in circle, we see that smaller circle (white circle) has radius 5 and big circle has radius 10. therefore we can find area of shaded area by doing

area of big - area of small

10²π - 5²π = 100π - 25π = 75π

circle in square, applying the same method, we can do square-circle

since the circle is inscribed in the square, the circle's diameter is 8, so its radius is 4

8²-4²π = 64-16π
