Question

The diameter of a circle measures 18yd . What is the circumference of the circle? Use3.14 for pie , and do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

Given ,

• The diameter of a circle measures 18yd

To Find : The Circumference of a circle

Radius can be the determined by the formula

`r = (d)/(2) \\r = (18)/(2) \\r = 9yd`

Now we can apply the formula of the circumference of a circle which is,

`Circumference = 2\pi r`

`Circumference = 2X3.14X9`

`Circumference = 56.52`

Hence , the Circumference of a circle is 56.52yd
