Answer:
79.74
Explanation:
Multiply 6 by 12 and that by 2:
(6 × 12) × 2 - (6 × 6) = 72 × 2 - 36= 144 - 36 = 108
That will be the equation for the shaded area besides the circle now lets calculate the circle and take it away from the equation. the circle's diameter is 6 so the radius should be 3, then use:
3 × 3 × 3.14 = 9 × 3.14 = 28.26
Then do this:
108 - 28.26 = 79.74
There you have it!
