Acircular garden has a diameter of 8 meters and is divided into 8 equal portions. a gardener wants to plant roses in every other section. what will remain for other types of flowers? note: 4 is not the right answer

The area of a circle with respect to its diameter is:

A=(πd^2)/4

If he plants roses in every other section, there will be half of the area remaining, so half of the area of the circle is:

A=(πd^2)/8, since d=8:

A=(64π)/8 m^2

A=8π  m^2  and if you want an approximation:

A≈25.13 m^2 (to nearest hundredth of a square meter)
