Question

A garden pond is 6 feet wide. The perimeter of the pond is 28 feet.

What is the area of the pond?

Answer 1

A garden pond = circle

Perimeter of a circle formula:
`2 \pi r`

r = radius

wide = diameter


`(diameter)/(2)` = radius

r =
`(wide)/(2)`

Area of a circle formula:
`\pi r^2`

Plug in:

`\pi ( (6)/(2) )^2`

`9 \pi`
