Question

Freyda has a circular rug with a radius of 120 centimeters. The fringe on the outside edge of the rug needs to be replaced. What is the approximate amount of fringe Freyda will use to the nearest centimeter?

Answer 1

The Fringe of the rug is 754 cm.

Explanation:

Given:

radius = 120 cm

We need to find the fringe of the outside rug.

Solution:

Since the rug is in the circular form.

We can say that fringe of the outside edge of the rug can be equal to circumference of the circle.

Then we will find the Circumference of the circle.

Circumference of the circle is given 2 times 'π' times radius 'r'.

framing in equation form we get;

Circumference of the circle =
`2\pi r`

Circumference of the circle =
`2 * \pi * 120 = 753.98 \approx 754\ cm`

Hence the Fringe of the rug is 754 cm.
