Calculate Circle Radius: Converting 50.25 Circumference

π ≈ 3.14 is a common approximation that makes calculations easier. For most practical problems, this gives sufficiently accurate results. You might also see π ≈ 3.14159 for more precision.

Circumference measures the distance around the circle using $C = 2\pi r$. Area measures the space inside using $A = \pi r^2$. Don't mix them up!

Divide both sides by $2\pi$: $r = \frac{C}{2\pi}$. With π = 3.14, this becomes $r = \frac{C}{6.28}$.

Since we're using π ≈ 3.14 instead of the exact value, calculations may have small rounding differences. Getting 7.99 or 8.01 is normal - round to the nearest whole number when appropriate.

Yes! Most calculators have a π button that gives more decimal places. However, for this problem using π = 3.14 matches the expected answer format.
