Question

Which statements about the design are true? select three options. each sprinkler head is placed more than 3 feet from the walkway. if two additional sprinkler heads are placed on the lawn, every square foot of the yard would be watered. the total area watered by each sprinkler is approximately 63.6 square feet. the total area watered by all the sprinklers is approximately 254 square feet. if the sprinklers were placed in two straight lines on the yard, they would water a greater amount of the lawn.

Answer 1

The true statements are:

• A. Each sprinkler head is placed more than 3 feet from the walkway.
• C. The total area watered by each sprinkler is approximately 63.6 square feet.
• D. The total area watered by all the sprinklers is approximately 254 square feet.

Calculations and Parameters:

Given that:

• Sprinkler head = More than one grid box away
• Each grid= 3 feet
• Sprinkler distance= 1.5 boxes
• Radius=?
• Area=?

To find the radius, 3 * 1.5= 4.5 feet.

The area of each circle=

$3.15(4.5)^2 \\= 63.585 \\ 63.6 ft^2.$

Hence, the statements that are true are options A, C, and D.
