Answer 3

I don't think it is called law of sines sorry im not sure what it is called

Answer 4

To get the area of the sector of the circle, use a proportion.

The degree measure(25) of the sector is to the entire circle (360) as A, the area of the sector, is to the area of the circle, pi*r^2. r = 12.5/2.

Answer 5

25/360 = A /π*(6.25)²

Cross multiply and solve for A, the area of the sector.
