Suppose Clara has a collection of old CDs. If the diameter of a CD measures about 12 centimeters, approximate the circumference of the CD. Round your answer to the nearest tenth of a centimeter.

The circumference of the CD is approximately 38 cm

Step-by-step explanation:

The circumference of the CD can be seen as the distance around the CD.

The word "circumference"  is used to describe the perimeter of circular objects.

To find an approximate value of the circumference of the CD, we will use this formula.

Circumference = π × diameter

let us take π to be = 3.142

∴ circumference = 3.142 × 12 = 37.6991 cm

we can round this up to teh nearest tenth as 38cm
