The area of a circle can be calculated using the formula A = πr², where A is the area and r is the radius of the circle.
Given that the diameter of the circle is 10 millimeters, we can find the radius by dividing the diameter by 2.
Radius = Diameter / 2 = 10 mm / 2 = 5 mm
Now, we can substitute the radius into the formula to find the area:
A = πr² = 3.14 * (5 mm)² ≈ 3.14 * 25 ≈ 78.5 mm²
Since the question asks for the area to the tenths place, we round the area to one decimal place:
Area ≈ 78.5 mm² (rounded to the tenths place)
that is the area of a circle with a diameter of 10 millimeters? Estimate the area to the tenths place using 3 14 for m (1 point)
