How much of the circle is shaded? Write your answer as a fraction in simplest form

5/21

Step-by-step explanation:

add the two unshaded portions and subtract that from 21/21, or 1 whole

3/7 = 9/21

1/3 = 7/21

sum of unshaded portions is equal to 16/21

21/21 - 16/21 = 5/21

I think it may be 2/4 or 4/10

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
