Step-by-step Solution
Para encontrar o valor de \( C \) quando \( r = 10 \, \text{km} \), precisamos usar a fórmula para calcular o comprimento de um círculo, que é dada por:
\[ C = 2 \pi r \]
Substituindo \( r = 10 \, \text{km} \) na fórmula, temos:
\[ C = 2 \pi \times 10 \]
Agora, podemos calcular o valor de \( C \) em metros.
Calculate the value by following steps:
- step0: Calculate:
\(2\pi \times 10\)
- step1: Multiply the terms:
\(20\pi \)
O valor de \( C \) é aproximadamente \( 62.831853 \, \text{m} \).
Quick Answer
\[ C = 2 \pi \times 10 \]
\[ C \approx 62.831853 \, \text{m} \]
