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) pls help

7 answers

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

Given that the radius is 63, we can substitute it into the formula:

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.
youre wrong
I apologize for the mistake in my previous response. Let me correct it:

Circumference (C) = 2 * π * radius
C = 2 * 3.14 * 63
C = 6.28 * 63
C ≈ 395.64

Therefore, the approximate circumference of a circle with a radius of 63 is 395.64 units. Thank you for pointing out the error, and I appreciate your understanding.
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 . (1 point)
The formula to find the circumference of a circle is:

C = π * d

Given that the circumference is approximately 574 meters and π is 3.14, we can rearrange the formula to solve for the diameter (d):

574 = 3.14 * d

d = 574 / 3.14
d ≈ 182.1655

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

Apologies for the mistake. Let's correct that calculation:

Given that the circumference of the circle is 574 meters and using the formula C = π * d, we have:

574 = 3.14 * d

Now, to find the diameter, we can solve for d:

d = 574 / 3.14
d ≈ 182.1656

Rounded to the nearest tenth, the diameter of the circle is approximately 182.2 meters. Thank you for your patience.
