Calculate the circumference of the inscribed circle. [Use π = 3.14]
A) 18.84 ft
B) 37.68 ft
C) 48 ft
D) 75.36 ft

B) 37.68 ft

Step-by-step explanation:

The diameter is 12 because the square's side is 12. The circumference is diameter * pi. 12 * 3.14 = 37.68.

Hope I Helped

whats the question?

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
