Question

A circular table has a radius of 2 1/2ft. Find its circumference

Answer 1

Given:

The radius of the circle is 2 1/2 ft.

To find:

The circumference of the circle

Step-by-step explanation:

Using the formula of the circumference of the circle

`C=2\pi r`

On substitution we get,

`\begin{gathered} C=2*(22)/(7)*2(1)/(2) \\ =2*(22)/(7)*(5)/(2) \\ C=(220)/(14)ft \\ C=(110)/(7)ft \\ C=15(5)/(7)ft \end{gathered}`

Final answer:

The circumference of the circle is,

`\begin{gathered} (110)/(7) \\ (or) \\ 15(5)/(7)ft \end{gathered}`

In decimal,

`C\approx15.71ft`
