Question

Elizabeth buys a circular rug with a lace border. The lace is 12.56 feet long.

What is the diameter of the rug? Round to the nearest whole number. (Use 3.14 for pi.)

Answer 1

The diameter of the rug is
`4\ ft`

Explanation:

we know that

The circumference of a circle (circular rug) is equal to

`C=\pi D`

where

D is the diameter of the circle

In this problem we have

`C=12.56\ ft`

substitute in the formula and solve for D

`12.56=(3.14)D`

`D=12.56/(3.14)=4\ ft`
