Question

If a circle has a radius of thirty eight inches what is the approximate circumference to the nearest hundreds use 3.14 for

Answer 1

To find the circumference of a circle, you can use the formula:

\[
C = 2\pi r
\]

where \( C \) is the circumference and \( r \) is the radius. Given that the radius \( r \) is 38 inches and using \( \pi \approx 3.14 \), the calculation would be:

\[
C = 2 \times 3.14 \times 38
\]

Calculating the multiplication step-by-step:

1. Calculate \( 2 \times 3.14 = 6.28 \)
2. Now multiply that by 38:

\[
6.28 \times 38 \approx 238.64
\]

Rounding this to the nearest hundred gives you:

\[
\text{Circumference} \approx 200 \text{ inches}
\]

So, the approximate circumference of the circle to the nearest hundred is **200 inches**.
