Part a: a circle is the set of all points that are the same distance from one given point. find an example that contradicts this definition. how would you change the definition to make it more accurate?
part b: give an example of an undefined term and how it relates to a circle.

a)

a circle is a 2d shape. so if you were to make points from the same given point but on different planes you would make a sphere, which is a 3d shape.

the true definition for a circle would be:

a circle is the set of all points on the same plane that are the same distance from one given point.

b)

there are 3 undefined terms. they are a point, a line and a plane.

a point needs to be defines to give the circle a radius. a line is not part of a circle.

the plane is a part of a circle by the above given definition.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
