Step-by-step Solution
Para encontrar o valor de \( r \), precisamos usar a fórmula da circunferência de um círculo, que é dada por:
\[ C = 2 \pi r \]
Dado que \( C = 9 \, \text{m} \), podemos substituir esse valor na fórmula e resolver para \( r \):
\[ 9 = 2 \pi r \]
Agora, vamos resolver essa equação para encontrar o valor de \( r \).
Solve the equation by following steps:
- step0: Solve for \(r\):
\(9=2\pi r\)
- step1: Swap the sides:
\(2\pi r=9\)
- step2: Divide both sides:
\(\frac{2\pi r}{2\pi }=\frac{9}{2\pi }\)
- step3: Divide the numbers:
\(r=\frac{9}{2\pi }\)
O valor de \( r \) é \( r = \frac{9}{2\pi} \) metros.
Quick Answer
\( r = \frac{9}{2\pi} \) metros.
