Question

the circumference of a circle is 12.56 centimeters. what is the circle’s diameter? c = 12.56 cm round your answer to the nearest hundredth. blank centimeters submit

Explanation:

Step1: Recall the formula for the circumference of a circle.

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter and \( \pi \approx 3.14 \).

Step2: Solve for the diameter \( d \).

We know \( C = 12.56 \) cm and \( C = \pi d \), so we can rearrange the formula to \( d=\frac{C}{\pi} \). Substituting the given values, we get \( d = \frac{12.56}{3.14} \).

Step3: Calculate the value.

Performing the division \( \frac{12.56}{3.14}=4 \). Since we need to round to the nearest hundredth, and 4 is an integer, we can write it as 4.00 (to the nearest hundredth).

Answer:

4.00
