The area covered by all the sprinkler heads together is approximately 169.61 square feet. Then the correct option is B.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The irrigation design for a new backyard is shown with six sprinkler heads and two walkways.
The value of radius is 3 feet.
Then the total area of circles will be
A = 6πr²
A = 6 x π x 3²
A = 6 x 9 x π
A = 169.61 square feet
