Answer:
c=2πr
Step-by-step explanation:
Multiply 2 by pi and the radius. If you don't have a calculator you could just multiply 2x3.14r instead of all of pu
The first one doesn't help while both the second and third helps in finding the vertices
always
i got it right
So in order to get all the fractions to have a common denominator, we need to multiply by , and by :
Now,
As long as and (which we can't have because otherwise ), we can cancel in the denominators on both sides:
We can factorize the right side:
which tells us that and are solutions.
2/3
If we divide both 8 and 12 by 4, we would get 2 and 3. 2/3
