Question

The fence around a circular garden is 18 feet long. What is the area of the garden to thenearest square foot? Use 3.14 for pi.Type the answer in the box.square feet

Answer 1

We will determine the area of the circular garden as follows:

*First: We obtain values by solving for the circumference of a cicle, that is:

`C=2\pi r\Rightarrow18=2\pi r`

Now, we solve for the radius:

`\Rightarrow r=(9)/(\pi)`

*Second: We determine the area of the cirular garden:

`A=\pi r^2\Rightarrow A=(3.14)((9)/(3.14))^2`
`\Rightarrow A=25.79617834\Rightarrow A\approx26`

So, the area of the circular garden is approximately 26 square feet.
