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.(1 point)

The approximate circumference can be found using the formula C = 2πr, where r is the radius.

C = 2 * 3.14 * 63
C = 395.64

Therefore, the approximate circumference of a circle with a radius of 63 is 395.64.

The circumference of a circle can be found using the formula C = πd, where d is the diameter.

Given the diameter is 20, we can calculate the circumference:

C = 3.14 * 20
C = 62.8

Therefore, the approximate circumference of a circle with a diameter of 20 is 62.8.

If a circle has a radius of 38 inches, what is its approximate circumference to the nearest hundredths? Use 3.14 for π .(1 point)

To find the diameter of the circle when given its circumference, we can use the formula for the circumference of a circle: C = πd, where C is the circumference and d is the diameter.

Given the circumference is 574 meters and using π = 3.14:

574 = 3.14 * d
d = 574 / 3.14
d ≈ 182.16560509554140

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

The formula to calculate the circumference of a circle is C = 2πr, where r is the radius.

Given that the radius is 38 inches and using π = 3.14:

C = 2 * 3.14 * 38
C = 239.36 inches

Therefore, the approximate circumference of a circle with a radius of 38 inches is 239.36 inches rounded to the nearest hundredths.

The correct formula to find the circumference of a circle with a radius of 12 is C = 2πr.

Given that the radius is 12 and π = 3.14:

C = 2 * 3.14 * 12
C = 75.36

Therefore, the correct answer is 75.36.

Among the provided options, the correct choice is:
75.36
