Step 1) Find out how much of the circle we need to find the area of
In the missing piece of the circle, we can see a right angle, or 90 degrees. Let's find the fraction of the circle that is remaining.
360 - 90 = 270
Remaining fraction: 270/360 = 3/4
Step 2) Find the area of the whole circle
A = pi x r^2
A = pi x 4^2
A = 16pi
Step 3) Use the fraction we found in step 1 and multiply that fraction by the area of the whole circle
16pi x 3/4 = 12pi
A = 12pi = 37.68 units^2
Hope this helps! :)
