Let's solve this step by step.
First, we need to find the *radius* of the circle, which is half the diameter. Since the diameter is given as 12 meters, to find the radius, we divide this by 2. So:
Radius = Diameter / 2
Radius = 12 meters / 2
Radius = 6 meters
Now, we will calculate the *circumference*, which is the distance around the circle. The formula to calculate the circumference of a circle is:
Circumference = π * Diameter
Here, π (Pi) is a constant with a value approximately equal to 3.14159. We will use this value for π to calculate the circumference.
Given the diameter is 12 meters, we plug this value into the formula:
Circumference = π * 12 meters
Circumference ≈ 3.14159 * 12 meters
Circumference ≈ 37.69908 meters
Lastly, we will round the radius and the circumference to the nearest whole number:
- The radius is already a whole number, so it remains 6 meters.
- The circumference, when rounded to the nearest whole number, is approximately 38 meters.
The correct choices based on our calculations are:
Radius = 6 meters
Circumference = 38 meters
Thus, the closest options that match our rounded answers are:
Radius 6 m, circumference = 38 m
