Answer:

70.38 cm

Step-by-step explanation:

π = 3.14

Area of a circle = πr^2

394.38 = πr^2

125.598726 = r^2

r = 11.2070837 cm

Circumference = 2πr

C = 70.3804856 cm

Step-by-step explanation:

3x-4y=13

y=-3x-7

3x-4(-3x-7)=13

3x+12x+28=13

15x=-15

x= -1

y= -3x-7 = 3-7= -4

Answer:

Option C

Step-by-step explanation:

Find the equation of the graphed line.

Use 2 points, (0, -6) and (2, 4)

m = (4 + 6)/2 = 5
b = -6

The equation is:

y = 5x - 6

Compare with the given line y = 4x + 2

5 > 4 and -6 < 2

Correct answer choice is c
