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.(1 point) Responses 78.5 square mm 78.5 square mm 79 square mm 79 square mm 15.7 square mm 15.7 square mm 314 square mm
The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle and π is approximately 3.14.
Given that the diameter is 10 mm, the radius is half of the diameter, so the radius is 5 mm.
Therefore, the area of the circle is A = π(5)^2 = 3.14 * 25 = 78.5 square mm.
So, the estimated area to the tenths place is 78.5 square mm.
The correct response is:
78.5 square mm
