Answer:
Option C. 154 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Pi (π) = 22/7
Diameter (d) = 14 cm
Area (A) =?
Next, we shall determine the radius of the circle. This can be obtained as follow:
Diameter (d) = 14 cm
Radius (r) =?
r = d/2
r = 14/2
r = 7 cm
Finally, we shall determine the area of the circle as illustrated below:
Pi (π) = 22/7
Radius (r) = 7 cm
Area (A) =?
The area of a circle can be obtained by using the following formula:
A = πr²
A = 22/7 × 7²
A = 22/7 × 7 × 7
A = 22 × 7
A = 154 cm²
Thus, the area of the circle is 154 cm²

Answer:
Step-by-step explanation:
I find it convenient to use a graphing calculator to graph the function.
The "start" is x=0, where the distance from the sprinkler head is 0 feet. The value of h(0) is 9.5, the height of the sprinkler head.
- The irrigation system is positioned <u> 9.5 </u> feet above the ground.
The graph shows the vertex of the curve is (5, 34.5), meaning that a height of 34.5 feet is reached 5 feet horizontally from the sprinkler.
- The spray reaches a <u> maximum </u> height of <u> 34.5 </u> feet at a horizontal distance of <u> 5 </u> feet away from the sprinkler head.
- The spray reaches all the way to the ground at about <u> 10.9 </u> feet away.
The graph shows the x-intercept at about 10.9. That is where the height of the spray is 0 feet above the ground.
