Answer:
2.39 meter
Step-by-step explanation:
Let r be the radius of the circular swimming pool and A be the area of circular swimming pool.
Given.
The area of circular swimming pool is [tex]18m^{2}[/tex]
[tex]A = 18[/tex]
The area of circle = [tex]\pi r^{2}[/tex]
[tex]A=\pi r^{2}[/tex]-------(1)
Put A value in equation 1.
[tex]18=\pi r^{2}[/tex]
[tex]r^{2}=\frac{18}{\pi }[/tex]
Put [tex]\pi =\frac{22}{7}[/tex] value.
[tex]r=\sqrt{ \frac{18}{\frac{22}{7} }[/tex]
[tex]r=\sqrt{\frac{18\times 7}{22} }[/tex]
[tex]r=\sqrt{ \frac{126}{22} }[/tex]
[tex]r=\sqrt{5.72}[/tex]
[tex]r=2.39mtere[/tex]
The radius of the circle is 2.39 meter.
