Question

A circle of yellow tulips is planted in Cedarburg's central park. Pam measured the circle and calculated that is has a circumference of 12.56 yards. What is the circle's diameter? Use 3.14 for ​.

Answer 1

The circle's diameter is
`4\ yd`

Explanation:

we know that

The circumference of a circle is equal to

`C=\pi D`

where

D is the diameter of the circle

In this problem we have

`C=12.56\ yd`

`\pi=3.14`

substitute the values and solve for D

`12.56=(3.14)D`

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