are you sure
I apologize for the error in my response. Let me correct it with the accurate calculation:
The radius of the circle is half the diameter, so the radius is 10 mm / 2 = 5 mm.
The formula for the area of a circle is A = πr^2, where r is the radius.
Substitute in the values:
A = 3.14 x (5)^2
A = 3.14 x 25
A = 78.5 square mm
Therefore, the area of the circle with a diameter of 10 millimeters is 78.5 square mm.
