Find the radius (r) of a circle with a circumference of 43.96 feet.
d = C ÷ π/2
Use 3.14 for π

1 answer

To find the radius (r) of a circle from its circumference (C), we can use the formula for the circumference of a circle:

\[ C = 2\pi r \]

Given that the circumference (C) is 43.96 feet, we can plug in the value of C and solve for r using the value of π as 3.14:

\[ 43.96 = 2 \cdot 3.14 \cdot r \]

Now, we can rearrange the equation to solve for r:

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

Substituting the values in:

\[ r = \frac{43.96}{2 \cdot 3.14} \]

Calculating the denominator:

\[ 2 \cdot 3.14 = 6.28 \]

Now we can substitute that back into the equation for r:

\[ r = \frac{43.96}{6.28} \approx 7.006 \]

So, the radius (r) of the circle is approximately 7.01 feet (rounded to two decimal places).
