Question

What is the circumference of a circular park with a radius of 100 meters? (round your answer to the nearest tenth) a. 314.1 m b. 1256.6 m c. 157.1 m d. 628.3 m

Answer 1

Explanation:

The circumference of a circular park can be calculated using the formula C = 2πr, where C represents the circumference and r represents the radius of the circle.

Given that the radius of the circular park is 100 meters, we can substitute this value into the formula and solve for the circumference.

C = 2π(100)

C = 200π

To find the value of C to the nearest tenth, we can approximate the value of π as 3.14.

C ≈ 200(3.14)

C ≈ 628.3

Therefore, the circumference of the circular park with a radius of 100 meters is approximately 628.3 meters. The correct answer is option d.

Answer 2

Answer: 628.3 m

Explanation:

In order to find the circumference, apply the formula:

`\bullet\quad\sf{C=2\pi r}`

where r is the radius.

Substitute 100 for the radius:

`\bullet\quad\sf{C=2*\pi*100}`

`\bullet\quad\sf{C=628.3\:m}`

Therefore, the circumference is 628.3 m.
