Question

substitute the given values into the given formula and solve for the unknown variable. if necessary, rou c = 2πr, c = 59.7 (circumference of a circle) r = □

Explanation:

Step1: Isolate the variable $r$.

Given $C = 2\pi r$, we can solve for $r$ by dividing both sides of the equation by $2\pi$. So $r=\frac{C}{2\pi}$.

Step2: Substitute the value of $C$.

We know that $C = 59.7$. Substituting this into the formula for $r$, we get $r=\frac{59.7}{2\pi}$.

Step3: Calculate the value of $r$.

Using $\pi\approx3.14$, we have $r=\frac{59.7}{2\times3.14}=\frac{59.7}{6.28}\approx9.5$.

Answer:

$9.5$
