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)

Step-by-step explanation:
a2=a1+1/2=-1
a3=a2+1/2=-1/2, then we have common difference 0.5
a9=a1+(n-1)d
a9=-3/2+(8)0.5=5/2
