The circumference of a circle can be found using the formula: C = πd, where C is the circumference and d is the diameter.
Given that the diameter is 3.25 meters, we can substitute it into the formula:
C = 3.14 * 3.25
C ≈ 10.21 meters
Therefore, the estimated circumference of the circle is 10.21 meters.
What is the circumference of a circle with a diameter of 3.25 meters? Estimate the circumference to the hundredths place using 3.14 for π.

What is the circumference of a circle with a diameter = 4 feet? Which of the following is the best estimation for the circumference?
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter is 4 feet, we can substitute it into the formula:
C = 3.14 * 4
C = 12.56 feet
Therefore, the exact circumference of the circle is 12.56 feet.
However, you mentioned "the following" without providing any options to choose from, so I cannot determine which estimation would be the best in this case.
Given that the diameter is 4 feet, we can substitute it into the formula:
C = 3.14 * 4
C = 12.56 feet
Therefore, the exact circumference of the circle is 12.56 feet.

The area of a circle is given by the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius.
Given that the diameter is 10 millimeters, we can divide it by 2 to find the radius:
Radius = 10 mm / 2 = 5 mm
Now we can substitute the radius into the formula:
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5 square mm
Therefore, the exact area of the circle is 78.5 square mm.
