Can someone help me with this please?

a.) 33.51
b.) 8.38

The formula for finding the area of a sector is (angle)/360 • area of circle, so A is 33.51
As for the length of the sector, we need the circumference of the circle (which is 50.27). Then, we can do 360/60 to get 6. Now, we divide 50.27/6 to get the length of the sector. So, B is 8.38.

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
