, where theta is the angle in radians. For us, the formula looks like this:  
. Doing all the multiplication on that gives us 
. Multiplying in pi and rounding to the nearest tenth gives us an area of 76.3 meters squared. You can use the formula for the area of a sector with the angle in degrees as well. Just replace the 360 degrees with 2pi and it works the exact same way.
