Question

the radius of a circle is 19 centimeters. what is the circles circumference? round your answer to the nearest hundredth. centimeters submit

Explanation:

Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius.

Step2: Substitute the radius value

Given \( r = 19 \) cm, substitute into the formula: \( C = 2\times\pi\times19 \).

Step3: Calculate the value

First, \( 2\times19 = 38 \), so \( C = 38\pi \). Using \( \pi \approx 3.14159 \), we get \( C \approx 38\times3.14159 \approx 119.38242 \).

Step4: Round to nearest hundredth

Rounding \( 119.38242 \) to the nearest hundredth gives \( 119.38 \).

Answer:

119.38
