what would be the answer cause it makes no sense to me
Find the radius of Circle P if its endpoints are (-4, 3) and (2, -1).
along with this one
In a circle, a minor arc = 20x + 15 and the major arc = 30x + 45. Find the length of the major arc.

I guess by endpoints they mean opposite ends of a diameter
so
the radius is half the distance between the two points
range in x = 2 + 4 = 6
range in y = 3 + 1 = 4
diameter^2 = 16 + 36 = 52
so diameter = sqrt 52 = 7.21
and radius = 3.6

The sum of the major arc and the minore arc is the circumference 2 pi R or pi D
so
20 x+15 + 30 x + 45 = pi D
50 x + 60 = pi D
That is all I can say without knowing D or R

20 x+15 + 30 x + 45 = pi D
