The area of a circle can be found using the formula A = πr^2, where r is the radius of the circle. In this case, the diameter is given as 10 millimeters, so the radius would be half of that, which is 5 millimeters.
Using the estimated value of π as 3.14, we can calculate the area as follows:
A = 3.14 * (5)^2
A = 3.14 * 25
A ≈ 78.5
Therefore, the estimated area of the circle is 78.5 square millimeters, rounded to the tenths place.
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
