Explanation:
The equation of the circumference is:
[tex]C=2\pi r[/tex]
Where r is the radius of the circle. Also, since 2 times the radius is the diameter the equation above can be written as:
[tex]C=\pi D[/tex]
Where D is the diameter of the circle.
For this problem the line we have to multiply by pi to find the circumference is the one that represents the diameter. In this case this line is QS
Answer:
• QS
