You have to first find the diameter of the circle which is the line segment that passes through the center of the circle and the endpoints lie on the circle.
The diameter is 12. I counted the units from left side to the center point and to the right side.
The formula for area of a circle is A= πr^2 The radius is half of the diameter which is 6.
A = π(6^2) =36 π = 113.0973355292326 or simplified to A= 113.1 square units.
