Area of circle is given as:
Where
To find radius of a circle circumscribing an equilateral triangle, we use the expression
Where, a is the length of sides of the equilateral triangle. Therefore:-
We can then proceed and calculate the area of the circle as follows:-
*The attached picture illustrates what the circumscribed equilateral triangle looks like
Answer:
22
Step-by-step explanation:
The standard form for an equation of a circle is , where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius of the circle. Therefore, the radius of this circle squared is 121, meaning that the radius of the circle is 11. Since the diameter of a circle is twice the radius, the radius of this circle is 22. Hope this helps!
