Step-by-step explanation:
The equation for a circle is
This should tell you that in order to write the equation for a circle, you need either the center and a point and then solve for the radius, or you need 2 points ON the circle that will help you find the center (it would be exactly between those 2 points so you could use the midpoint formula to find the center and then you would have the h and the k and can take it from there.)
The definition of a circle is the locus of all points that is equidistant from a point in space. That point in space is the center and all the points equidistance from it are ON the circle, not inside the circle.
Hope that helps.
Answer:
= 98 + 7c or = 7(14+c)
Step-by-step explanation:
7(6+c+8)
7*6 + 7c + 7*8
= 42 + 7c + 56
= 98 + 7c
= 7(14+c)
