Question

1. in circle p, xy = 2.4 cm. what is the circumference of the circle? 1.2π cm 4.8π cm 2.4π cm 3.6π cm

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Identify the diameter of the circle

From the problem, we know that \(XY\) is the diameter of the circle \(P\), and \(XY = 2.4\) cm. So \(d=2.4\) cm.

Step3: Calculate the circumference

Substitute \(d = 2.4\) into the formula \(C=\pi d\). We get \(C = 2.4\pi\) cm.

Answer:

\(2.4\pi\) cm (the third option)
