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?

Sagot :

Answer:

1256.64 square feet

Step-by-step explanation:

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

Use the area formula, A = [tex]\pi[/tex]

Plug in 20 as the radius and solve:

A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](20)²

A = 400[tex]\pi[/tex]

This is approximately equivalent to 1256.64

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