Question

  1. circle a has a radius of 24.2 centimeters. what is the circumference, in centimeters, of circle a rounded to the nearest hundredth? centimeters

Explanation:

Step1: Escribir la fórmula de la circunferencia

La fórmula de la circunferencia de un círculo es \( C = 2\pi r \), donde \( r \) es el radio.

Step2: Sustituir el valor del radio

Dado que \( r = 24.2\ \text{cm} \), sustituimos en la fórmula: \( C = 2\times\pi\times24.2 \).

Step3: Calcular el valor

Tomando \( \pi\approx3.14159 \), \( C = 2\times3.14159\times24.2\).

Answer:

\( 151.05\ \text{cm} \)
