the endpoints of a of a circle "" are
(-10, 5) and (4, 5).
What is the of circle ""

the of circle is:
so, we need to find out what is equal
given:
the endpoints of a of a circle (-10, 5) and (4, 5)
the distance between then is equal to a
let's find the distance between (-10, 5) and (4, 5)

Solved by pluggable solver: Distance Formula to determine length on coordinate plane
The distance (d) between two points is given by the following formula:



Thus in our case, the required distance is



For more on this concept, refer to Distance formula.



so, the distance
we know that ...so,
now we can find
