Find the radius (r) of a circle with a circumference of 56.52 feet.
r = C ÷ π/2
Use 3.14 for π

1 answer

To find the radius (r) of a circle given the circumference (C), you can use the formula for the circumference of a circle, which is:

\[ C = 2\pi r \]

Given that:

\[ C = 56.52 \text{ ft} \]

We can rearrange the formula to solve for the radius (r):

\[ r = \frac{C}{2\pi} \]

Now, substituting the values and using \( \pi \approx 3.14 \):

\[ r = \frac{56.52}{2 \times 3.14} \]

Calculating the denominator:

\[ 2 \times 3.14 = 6.28 \]

Now substituting back into the equation:

\[ r = \frac{56.52}{6.28} \]

Now, performing the division:

\[ r \approx 9.00 \text{ ft} \]

So the radius (r) of the circle is approximately 9.00 feet.
