Answer:
The area the sprinkler sprays with water is 201.06 square feet.
Step-by-step explanation:
Step 1; It is given that the diameter of the circular area of grass that the sprinkler sprays with water is 16 feet. The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.
Radius of the circle = Diameter of the circle / 2 = 16 feet / 2 = 8 feet.
Step 2; The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.
Area of the circle = π × r² = 3.1415 × 8 feet = 201.06 square feet
256² = (256)·(256) = 65,536
I don't understand what is writing but I think the answer could be (x+1)(x-5)
1696.46 square feet
2x(9x9xpi) for the circular ends
9x2xpi for the diameter of the circle the multiply by 30 for the surface area of the sides
Add together to get 1696.46 square feet
