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 314 square mm 314 square mm 15.7 square mm 15.7 square mm 79 square mm 79 square mm 78.5 square mm
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is 10 mm, the radius is half of the diameter, which is 5 mm.
Plugging in the values, the area of the circle is A = 3.14*(5)^2 = 3.14*25 = 78.5 square mm.
Therefore, the area of the circle with a diameter of 10 mm is estimated to be 78.5 square mm.
