If the circumference of a circle is 428 meters, what is the radius, rounded to the nearest hundredths place? Use 3.14 for 𝝅.

Answer 1

To find the radius of a circle, we can use the formula:

Circumference = 2 * 𝝅 * radius

Given that the circumference is 428 meters, we can plug in the values:

428 = 2 * 3.14 * radius
428 = 6.28 * radius

Now, divide both sides by 6.28 to solve for the radius:

radius = 428 / 6.28
radius ≈ 68.15

Rounded to the nearest hundredths place, the radius of the circle is approximately 68.15 meters.
