Answer:
There are no solutions
Step-by-step explanation:
Because the lines are parallel, they will never meet, meaning there are no solutions to this system of equations
Step-by-step explanation:
the formula to calculate a circumference is
![x \times \pi](https://tex.z-dn.net/?f=x%20%5Ctimes%20%5Cpi)
(consider x as the diameter)
so I'll be noting the circumference as C alongside the circle's ranking
a.
![ca = 6 \times 22 \div 7 \\ = 44 \div 7](https://tex.z-dn.net/?f=ca%20%3D%206%20%5Ctimes%2022%20%5Cdiv%207%20%5C%5C%20%20%3D%2044%20%5Cdiv%207)
b.
![cb = 7 \times 22 \div 7 \\ = 154 \div 7 \\ = 22](https://tex.z-dn.net/?f=cb%20%20%3D%207%20%5Ctimes%2022%20%5Cdiv%207%20%5C%5C%20%20%3D%20154%20%5Cdiv%207%20%5C%5C%20%20%3D%2022)
c.
![cc \: = 4 \times 22 \div 7 \\ = 88 \div 7](https://tex.z-dn.net/?f=cc%20%5C%3A%20%20%3D%204%20%5Ctimes%2022%20%5Cdiv%207%20%5C%5C%20%20%3D%2088%20%5Cdiv%207%20)
hope I helped
