The circumference of a circle can be calculated using the formula C = πd, where d is the diameter of the circle.
Given that the diameter is 20, we can plug it into the formula:
C = 3.14 * 20
C ≈ 62.8
Therefore, the approximate circumference of a circle with a diameter of 20 is 62.8.

The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.
Given that the circumference is 574 meters, we can rearrange the formula to solve for the diameter:
d = C / π
d = 574 / 3.14
d ≈ 182.2
Therefore, the circle's diameter, rounded to the nearest tenth, is approximately 182.2 meters.
Given that the circumference is 574 meters, we can rearrange the formula to solve for the diameter:
d = C / π
d = 574 / 3.14
d ≈ 182.2
Therefore, the circle's diameter, rounded to the nearest tenth, is approximately 182.2 meters.

To find the diameter of the circle given the circumference of 574 meters, we can use the formula:
Circumference = π * diameter
Given that the circumference is 574 meters and π ≈ 3.14, we can solve for the diameter:
574 = 3.14 * diameter
diameter = 574 / 3.14
diameter ≈ 182.166
Rounded to the nearest tenth, the circle's diameter is approximately 182.2 meters.
Circumference = π * diameter
Given that the circumference is 574 meters and π ≈ 3.14, we can solve for the diameter:
574 = 3.14 * diameter
diameter = 574 / 3.14
diameter ≈ 182.166
Rounded to the nearest tenth, the circle's diameter is approximately 182.2 meters.
