A circle cannot have its circumference and area both equal to 246. The only possible equal values are circumference = 12.6 units area = 12.6 square units which are achieved by a circle with radius 2 units.
a circumference is a point in which two lines meet and the area is=pie R
It has an area of 900π, which is about equal to 2827.43339 It has a circumference of 60π, which is about equal to 188.49556
The area of a circle is equal to the perimeter times half the radius. That is, A = P*r/2
Please note that a circumference is a linear measurement (for example, meters), while area is an area measurement (for example, square meters), so the "equality" depends on the units used. Anyway, all you need to do is write the expression for the circumference, and the expression for the area, then put an equal sign in between - since the problem states that the two are equal. Then solve this equation.
