(a)
To find: An equation representing the farthest points the sprinkler can reach.
(a)
Answer to Problem 63SGA
Explanation of Solution
Given information: Gardening: Migina bought a new sprinkler that covers part or all of a circular area. With the center of the sprinkler as the origin, the sprinkler sends out water far enough to reach a point located at
Calculation:
Determine the radius:
The equation representing the farthest points is the circle with center
(b)
To find: The percent of her backyard will not be watered directly, if Migina waters her backyard without moving the sprinkler. Migina’s backyard is 40 feet wide and 50 feet long.

Answer to Problem 63SGA
Explanation of Solution
Given information: Gardening: Migina bought a new sprinkler that covers part or all of a circular area. With the center of the sprinkler as the origin, the sprinkler sends out water far enough to reach a point located at
Calculation:
Determine the area of backyard:
The area of backyard
Determine area of watered portion:
Area of watered portion
Determine the area of no watered portion:
Area of no water portion = Area of backyard − Area of watered portion
Conclude the percent:
Percent not watered
