The radius of a circle is half its diameter. In this case, the radius is (10 mm)/2 = 5 mm.
The formula to calculate the area of a circle is A = πr^2. Plugging in π as 3.14 and the radius as 5 mm, we can calculate the area.
A = 3.14 * (5 mm)^2
A = 3.14 * 25 mm^2
A = 78.5 mm^2
Therefore, the area of the circle is approximately 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
