Sides of a triangle is 4 units, 6 units, and 7.21 units.
We need to find the area of a circle with a circumference that equals the perimeter of the triangle.
Perimeter of triangle = circumference of circle
4+6+7.21=2πr, r is the radius of circle
r = 2.73 units
Area of circle,
or
A = 24 sq units
So, the area of the circle is 24 square units.
