My name is Tasha
I am a student and this is a secondary question.

I have a circle that has an equalateral triangle inscribed in it. The tip of the triangle (B) is at the center of the circle with the other corners (A & C) extending to the sides of the circle. I need to know the equation to find the linear length of AC. I also need to find the cordial length of the circle from point C to A.

Hi Tasha,

Draw a diagram!

Since ABC is an equilateral triangle the length of AC is the same as the length of AB. What is the length of AB?
