A semicircular flower bed has a diameter of 3 meters.
Diameter = 3 meters
Radius = [tex]\frac{diameter}{2}=\frac{3}{2} [/tex]
Area of circle = [tex]\pi r^2[/tex]
Area of semi circle = [tex]\frac{1}{2}\pir^2[/tex]
where r is the radius of the circle
Area of semi circle = [tex]\frac{1}{2} * \pi *\frac{3}{2}^2[/tex]
We use 3.14 for pi
Area of semi circle = [tex]\frac{1}{2} * 3.14 *\frac{3}{2}^2[/tex] = 3.5325
Area of semi circle = 3.53 [tex]m^2[/tex]
