Question

a circle has a diameter of 4 meters. what is the circumference of the circle in meters? use the formula ( c=pi d ) where ( c ) is the circumference of a circle and ( d ) is the diameter. ( 2pi ) ( 4pi ) ( 8pi ) ( 16pi )

Explanation:

Step1: Substitute the value of diameter into the formula

Given the formula \(C=\pi d\) and \(d = 4\) meters.

Step2: Calculate the circumference

Substitute \(d = 4\) into \(C=\pi d\), we get \(C=\pi\times4=4\pi\)

Answer:

\(4\pi\) (corresponding to the second option \(4\pi\))
