The diameter of a circle is 151 m. Find the circumference to the nearest whole number.

Answer :

To find the circumference of a circle when the diameter is given, you can use the formula for the circumference, which is:

[tex]\[ C = \pi \times d \][/tex]

where:
- [tex]\( C \)[/tex] is the circumference,
- [tex]\( \pi \)[/tex] (pi) is approximately 3.14159,
- [tex]\( d \)[/tex] is the diameter of the circle.

In this problem, the diameter of the circle is given as 151 meters.

1. First, multiply the diameter by pi:
[tex]\[ C = 3.14159 \times 151 \][/tex]

2. This gives a calculated circumference:
[tex]\[ C \approx 474.38049069205874 \][/tex]

3. Finally, we round the calculated circumference to the nearest whole number:
[tex]\[ \text{Circumference} \approx 474 \][/tex]

So, the circumference of the circle to the nearest whole number is 474 meters.
