Given:
Diameter of the circular area = 14 ft
Since the area of the grass is circular, to find the area in square feet that this sprinkler sprays with water apply the area of a circle is formula:
[tex]A=\pi r^2[/tex]Where:
[tex]\text{radius, r = }\frac{diameter}{2}=\frac{14}{2}=7[/tex]Take π = 3,14
Thus, we have:
[tex]\begin{gathered} A=\pi r^2 \\ \\ A=3.14\ast7^2 \\ \\ A=3.14\ast49 \\ \\ A=153.86\text{ square f}eet \end{gathered}[/tex]Therefore, the area in square feet that this sprinkler sprays with water is 153.86 square feet
ANSWER:
B. 153.86 square feet
