Question

The circumference of a circular garden is 157 feet. What is the radius of the garden? Use 3.14 for π and do not round your answer.

Answer 1

Given:

The circumference of a circular garden is 157feet.

Required:

To find the radius of the circular garden.

Explanation:

The formula for circumference of a circle is,

$C=2\pi r$

Here,

$C=157feet$

Put C into the above, we get

$\begin{gathered} 157=2\times\pi\times r \\ 157=2\times3.142\times r \\ 157=6.284r \\ r=\frac{157}{6.284} \\ r=24.984 \end{gathered}$

Final Answer:

The radius of the circular garden is,

$r=24.984feet$
