Explain why pqr is an equilateral triangle

PQ is a radius, as it reaches the center and an edge. So is PR, just in a different location. They are the same length because the edges of a circle is equidistant from the center. Given that circle P is congruent to circle Q, QR is a radius that is the same length as the two other sides. So, all of the sides have the same lengths. That means that the triangle is equilateral.

A.  0.375‬

B.  0.400

C.  I believe its the third option because I remember doing this

Step-by-step explanation:

When asking for the experimental probability you divide the number of spins depending (on the color they ask) by the total number of spins

When asking for theoretical probability you divide how many slices on the spinner (depending on the color they ask) by the total number of slices
