Question

The radius of a circle is 13 meters. What is the circle's circumference?

r=13 m
Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.

Answer 1

[AI-generated answer — Bot GPT 3.5]

Circumference = 2 * 𝜋 * r

Circumference = 2 * 3.14 * 13
Circumference = 81.64 meters

Therefore, the circle's circumference is approximately 81.64 meters.

Answer 2

The radius of a circle is 11 yards. What is the circle's circumference?

r=11 yd
Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.

Answer 3

[AI-generated answer — Bot GPT 3.5]

Circumference = 2 * 𝜋 * r

Circumference = 2 * 3.14 * 11
Circumference = 69.08 yards

Therefore, the circle's circumference is approximately 69.08 yards.

Answer 4

The circumference of a circle is 81.64 millimeters. What is the circle's diameter?

Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.

Answer 5

[AI-generated answer — Bot GPT 3.5]

To find the diameter of the circle, we use the formula for the circumference:

Circumference = 𝜋 * diameter

Given that the circumference is 81.64 millimeters and π is approximately 3.14:

81.64 = 3.14 * diameter

Now, we can solve for the diameter:

diameter = 81.64 / 3.14
diameter ≈ 26.00 millimeters

Therefore, the circle's diameter is approximately 26.00 millimeters.

Answer 6

The circumference of a circle is 18.84 miles. What is the circle's radius?

C=18.84 mi
Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.

Answer 7

[AI-generated answer — Bot GPT 3.5]

To calculate the radius of the circle, we will use the formula for the circumference of a circle:

Circumference = 2 * 𝜋 * radius

Given that the circumference is 18.84 miles and π is approximately 3.14:

18.84 = 2 * 3.14 * radius

Now, we can solve for the radius:

radius = 18.84 / (2 * 3.14)
radius ≈ 3 miles

Therefore, the circle's radius is approximately 3 miles.
