Sure! The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle.
Given that the diameter is 10 millimeters, the radius is half of the diameter, which is 5 millimeters.
Now, substitute the value of the radius into the formula:
A = π(5)^2
A = π * 25
A = 78.5 square mm
Therefore, the estimated area of the circle with diameter 10 millimeters to the tenths place using 3.14 for π is 78.5 square mm.
