The shaded sector is  60 degrees out of the ENTIRE circle's 360 degrees

Find the area of the ENTIRE circle by using   Area = pi r2

then multiply by   60 / 360   to get the answer in ft2

I don't understand. after I find the radius and divide 60/360 what do I do next? subtract it or something?

Find the area  of the circle =   pi * radius^2    =  pi * 30^2  =  900 pi  ft^2

Since  the  60 degree sector  is 1/6   of   360 degrees.....the   sector's area  =   900 pi / 6   =

150 pi  ft^2   CPhill  Mar 29, 2022

There are 360 degrees in a whole circle, you have 60 degrees.  SO you have   $$\frac{60}{360}$$   of a circel

The area of a whole cirlce is  $$A=\pi r^2$$

If this was the whole circle the area would be    $$\pi* 30^2 = 900\pi \;feet\;squared$$

SO the area of just the sector will be     $$\frac{60}{360}*\pi*900 \;\;feet squared$$

and you can do the calculation.
