The circumference of a circle can be calculated using the formula: circumference = π * diameter.
Given that the diameter is 3.25 meters and π is approximated to 3.14, the circumference would be: circumference = 3.14 * 3.25 = 10.21 meters.
Therefore, the best estimation for the circumference to the hundredths place would be 10.21 meters.
Given that the diameter is 3.25 meters and π is approximated to 3.14, the circumference would be: circumference = 3.14 * 3.25 = 10.21 meters.
Therefore, the best estimation for the circumference to the hundredths place would be 10.21 meters.

The circumference of a circle can be calculated using the formula: circumference = 2 * π * radius.
Given that the radius is 2.5 feet and π is approximated to 3.14, the circumference would be: circumference = 2 * 3.14 * 2.5 = 15.7 feet.
Therefore, the best estimation for the circumference to the tenths place would be 15.7 feet.
Given that the radius is 2.5 feet and π is approximated to 3.14, the circumference would be: circumference = 2 * 3.14 * 2.5 = 15.7 feet.
Therefore, the best estimation for the circumference to the tenths place would be 15.7 feet.

The area of a circle can be calculated using the formula: area = π * radius^2.
Given that the radius is 12 feet and π is approximated to 3.14, the area would be: area = 3.14 * 12^2 = 452.16 square feet.
Therefore, the best estimation for the area to the hundredths place would be 452.16 square feet.
Given that the radius is 12 feet and π is approximated to 3.14, the area would be: area = 3.14 * 12^2 = 452.16 square feet.
Therefore, the best estimation for the area to the hundredths place would be 452.16 square feet.

The area of a circle can be calculated using the formula: area = π * (diameter/2)^2.
Given that the diameter is 10 millimeters and π is approximated to 3.14, the radius would be half of the diameter = 10 / 2 = 5 mm.
Substituting the values into the formula: area = 3.14 * 5^2 = 3.14 * 25 = 78.5 square mm.
Therefore, the best estimation for the area to the tenths place would be 78.5 square mm.
Given that the diameter is 10 millimeters and π is approximated to 3.14, the radius would be half of the diameter = 10 / 2 = 5 mm.
Substituting the values into the formula: area = 3.14 * 5^2 = 3.14 * 25 = 78.5 square mm.
Therefore, the best estimation for the area to the tenths place would be 78.5 square mm.
