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 provided, we can use the formula for the circumference of a circle, which is:

[tex]\[ \text{Circumference} = \pi \times \text{diameter} \][/tex]

Here, the diameter of the circle is given as 151 meters.

1. Substitute the value of the diameter into the formula:

[tex]\[ \text{Circumference} = \pi \times 151 \][/tex]

2. Use the approximate value of [tex]\(\pi\)[/tex], which is about 3.14159, to perform the calculation:

[tex]\[ \text{Circumference} \approx 3.14159 \times 151 \][/tex]

3. Calculate the product:

[tex]\[ \text{Circumference} \approx 474.38049069205874 \][/tex]

4. Round the result to the nearest whole number:

The circumference, when rounded, is approximately 474 meters.

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