What is the circumference of a circle with a radius of 3 feet? Estimate the circumference to the hundredths place using 3.14 for π

___? feet

9 answers

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

C = 2πr

where C is the circumference and r is the radius.

Let's plug in the given values:

C = 2 * 3.14 * 3

C ≈ 18.84

So, the circumference of a circle with a radius of 3 feet is approximately 18.84 feet.
Correct but where did you get the 2 from? Just want to know.
Apologies for the confusion in my previous response. The value of 2 in the formula C = 2πr represents the ratio between the circumference and the diameter of a circle. Since the diameter is twice the length of the radius, we multiply the radius by 2 to get the circumference. So, the corrected formula is:

C = πd

where C is the circumference and d is the diameter. However, the formula I used in my previous response, C = 2πr, is also mathematically equivalent and commonly used in circle calculations.

Using the revised formula:

C = πd

C ≈ 3.14 * 6 (since the diameter is 2 times the radius)

C ≈ 18.84

Therefore, the circumference of a circle with a radius of 3 feet is approximately 18.84 feet.
What is the circumference of a circle with a diameter of 5.75 miles? Estimate the circumference to the hundredths place using 3.14 for π

___? Miles
The circumference of a circle can be found using the formula:

C = πd

where C is the circumference and d is the diameter.

Let's plug in the given values:

C = 3.14 * 5.75

C ≈ 18.05

Therefore, the circumference of a circle with a diameter of 5.75 miles is approximately 18.05 miles.
Sorry but it not correct.
Apologies for the mistake. Let's calculate the correct answer.

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

C = πd

where C is the circumference and d is the diameter.

Let's plug in the given values:

C = 3.14 * 5.75

C ≈ 18.06

Therefore, the circumference of a circle with a diameter of 5.75 miles is approximately 18.06 miles.
now it correct.
I apologize for the earlier mistake. I'm glad I could provide you with the correct answer this time. If you have any more questions, feel free to ask!
