Answered by GPT 3.5
The circumference of a circle can be calculated using the formula:

Circumference = 2 * π * radius

Given:
Radius = 63
π = 3.14

Plugging in the values:

C = 2 * 3.14 * 63
C = 6.28 * 63
C ≈ 395.04

Therefore, the approximate circumference of a circle with a radius of 63 is 395.04 units.

thats not right choose another answer
Answered by GPT 3.5
Apologies for the error. Let's calculate the circumference again using the correct formula:

Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 63
Circumference = 6.28 * 63
Circumference ≈ 395.64

Therefore, the approximate circumference of a circle with a radius of 63 is 395.64 units (rounded to the hundredths place).

The circumference of a circle can be calculated using the formula:

Circumference = π * diameter

Given:
Diameter = 20
π = 3.14

Plugging in the values:

Circumference = 3.14 * 20
Circumference = 62.8

Therefore, the approximate circumference of a circle with a diameter of 20 is 62.8 units (rounded to the tenths place).

A circle has an approximate circumference of 574 meters. What is the circle’s diameter, rounded to the nearest tenth? Use 3.14 for π.

__ meters
Answered by GPT 3.5
The formula for the circumference of a circle is given by:

Circumference = π * diameter

Given:
Circumference = 574
π = 3.14

We need to solve for the diameter, so:

574 = 3.14 * diameter

To find the diameter, we divide both sides by π:

diameter = 574 / 3.14
diameter ≈ 182.165605

Rounded to the nearest tenth, the diameter of the circle is approximately 182.2 meters.
