+64 A circle is circumscribed about an equilateral triangle with side lengths of 9 units each. What is the area of the circle, in square units? Express your answer in terms of pi.
+351 Equilateral triangle radius of circumcircle = s√3
Which means r=3√3
Area of a circle is Pi*r^2
Substitute to get Π(3√3)2
Which is equal to 27Π
The area of the circumcircle is 27Π−units2
