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? (5 points) Part B: Give an example of an undefined term and how it relates to a circle. (5 points)

Read below

Step-by-step explanation:

Part A: A more accurate definition of a circle would be "A circle is the set of all points that are the same distance from one given point, which is the center." This is more accurate because it specifies which point all the other points are equidistant from.

Part B: One undefined term that relates to a circle is "point." A circle has one point, the center, which all other points are the same distance from.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
