The answer depends on whether 2.3 millimetres is the radius or the diameter.
A circle with a radius of 23 units has an area of 1,661.9 square units.
Circle area = (Pai) r 2 where r is the radius. Area = 3.14 x 23 x 23 = 1661.06
The circumference of a circle with a 10 millimeter diameter is about 31.42 mm
Area = 415.48 ft2
Area of circle: pi*1.85 squared = 10.75 square meters to two decimal places
A circle with a radius of 11.5 miles has an area of 415.48 square miles.
The area is 1,661.9 square yards.
A circle with a 23 inch diameter has am area of 415.4756 sq inches (to 4 dp).
Area = 0.25*π*diameter2 or π*radius2 Diameter = 23 units gives an area of 415.48 square units
Area of circle: pi*23^2 = 1661 square meters rounded to the nearest whole number
A diameter is an undefined length across a circle. reaching the longest distance possible, from edge-to-edge, and crossing the center. There are infinitely many diameters in a circle. A millimeter is a measurement that is 0.001 of a meter, also 0.03937 inches. There is no correct answer to this question, unless a specific circumference, area, radius, or diameter of the circle were given. pi = 3.14159265 (simplified 3.14)
