Question

Elijah is planning a circular flower garden with a 12 foot diameter. He will put plastic edging along the flowerbed. How many feet of edging will Elijah need to enclose his flower garden? Round to the nearest tenth place. (Use 3.14 for π)

Answer 1

`37.7\ \text{foot}`

Explanation:

The length of the edging will be equal to the circumference of the circular flower garden.

Here, the diameter of the circular garden is
`d=12\ \text{foot}`

Circumference of a circle is given by

`C=\pi d\\\Rightarrow C=3.14* 12\\\Rightarrow C=37.68\approx 37.7\ \text{foot}`

The length of the edging is
`37.7\ \text{foot}`.
