Answer:

3.50

Step-by-step explanation:

C = 2πr

   or

C = πd

In this case we are using C = 2πr

C = 2πr

22 = 2 x 3.14 x r

22 = 6.28 x r

22/6.28 = 6.28r/6.28

3.503184713375796178343949044585987261 = r

But estimated is 3.50

Rudiy27

Answer:

m = -2

y-intercept = 4

Step-by-step explanation:

m = y2-y1/x2-x1

so

m = -2-4/3-0

=-2

y=mx+b

Substitute the coordinates into the equation to find b

4=-2(0)+b

4=b

so y intercept is 4

y=-2x+4
