Question

A lawn sprinkler can spray up to 20 feet. If it sprays in a circular pattern, what is the approximate area in square feet watered by the sprinkler?

Answer 1

1256.64 square feet

Explanation:

In this situation, 20 feet is the radius of the circle that is sprayed.

Use the area formula, A =
`\pi`r²

Plug in 20 as the radius and solve:

A =
`\pi`r²

A =
`\pi`(20)²

A = 400
`\pi`

This is approximately equivalent to 1256.64

So, the approximate area watered by the sprinkler is 1256.64 square feet
