Find the diameter of a circle with a circumference of 21.98 feet.

Answer :

The circumference of a circle can be found by the formula

[tex]S=2\cdot\pi\cdot r[/tex]

this can also be written in function of the diameter

[tex]S=\pi\cdot D[/tex]

From this formula we can find the diameter

[tex]D=\frac{S}{\pi}[/tex]

Using the information given, the diameter of the circle is

[tex]D=\frac{21.98}{\pi}=6.996\approx7ft[/tex]
