We did a weird experiment today with sector measurements, protractors, string compasses, and oatmeal creme pies (sorry if you missed it!). We cut away pieces of the oatmeal creme pie and measured the remaining part of the sector using the compass, ruler, protractor, and the formula for the area of a compass.
Don't forget that when the problem asks you for the REMAINING area of the sector, they are wanting you to do 360 - the given angle = the angle you want to use. This will be your central angle for the remaining sector. Then convert it into radians and plug it into the formula for the area.
