what is the approximate circumference of a circle that has a radius of 63? use 3.14 for π and express your answer to the hundredths place.
__
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
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).
What is the approximate circumference of a circle that has a diameter of 20? Use 3.14 for π and express your answer to the tenths 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
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.
