The radius of the circle is half of the diameter, so the radius would be 10 millimeters divided by 2, which is 5 millimeters.
Using the formula for the area of a circle, which is A = πr^2, we can substitute the radius into the formula and estimate the area.
A = 3.14 * 5^2
A = 3.14 * 25
A ≈ 78.5
Therefore, the estimated area of the circle is 78.5 square millimeters.
What is the area of a circle with a diameter of 10 millimeters? Estimate the area to the tenths place using 3.14 for π
