Question

A 360 degree rotating sprinkler that sprays water at a radius of 11 feet is used to water a lawn. What is the Area of the lawn that is watered by this sprinkler ?

Answer 1

Answer:

$Area=121\pi ft^2$ in terms of $\pi$.

Step-by-step explanation:

A 360 degree rotating sprinkler will water a full circular region of the lawn.

The area of this circular region is calculated using the formula:

$Area=\pi r^2$

where r=11 feet is the radius of the circular region covered.

We substitute the value of the radius into the formula to get:

$Area=\pi \times 11^2$

$Area=121\pi ft^2$ in terms of $\pi$.

This is approximately $380.1 ft^2$ to the nearest tenth
