Answer:
We find out area of circular garden and then find out area of circle formed by sprinkle. Then subtract area of sprinkle from that area of circular garden
Step-by-step explanation:
Area of circular garden=πr²
=22/7×10²
=22/7×100
=2200/7m²
Area of circle formed by sprinkle
=πr²
=22/7×[7/100]m²
=22/100m²
Now area which is remaining
2200/7-22/100
=314.2-0.22
=313.98m²
