Question

use the given information to complete the table. use 3.14 for π. then verify that π is the ratio of the circumference to the diameter for the circle. round each answer to the nearest hundredth, if needed. circle 1
diagram: circle with points c, d, e, ( d = 4 , \text{cm} )
enter the answer in each space provided. use numbers instead of words.
table: columns - circumference (( \text{cm} )), radius (( \text{cm} )), diameter (( \text{cm} )), ( pi = \frac{\text{circumference}}{\text{diameter}} ) with empty boxes

Explanation:

Step1: Find the radius

The radius \( r \) is half of the diameter \( d \). Given \( d = 4 \) cm, so \( r=\frac{d}{2}=\frac{4}{2} = 2 \) cm.

Step2: Calculate the circumference

The formula for the circumference \( C \) of a circle is \( C=\pi d \). Using \( \pi = 3.14 \) and \( d = 4 \) cm, we get \( C = 3.14\times4=12.56 \) cm.

Step3: Find the ratio of circumference to diameter

We know \( C = 12.56 \) cm and \( d = 4 \) cm. So the ratio \( \frac{C}{d}=\frac{12.56}{4}=3.14 \).
