What is the area of this shape?

9.4275

Step-by-step explanation:

First you find the area of the circle without the cut portion which is

2 times 2 = 4. Then 4 times 3.14 = 12.57.

Now that we found the total area of the circle we need to subtract the removed portion. What you can see here is that the circle is cut by 25% so that means only 75% of it still remains. 75% of 12.57 is = 0.75 multiplied by 12.57 which is 9.4275

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
