1.	A cicalar Blower bed is of radius 3.5 m. If J kg of fentilizer is roquired for I square mtre anca, howmuch fertilizer will be required for the flower bed?
Answer» => Radius of the circular flower bed = 3.5 m => Area of the circular flower bed = π × r^2= 22/7 × (3.5)^2= 22/7 × 12.25= 22 × 1.75= 38.5 m^2 => Fertilizer required for 1 m^2 = 1/2 kg = 0.5 kg => Fertilizer required for 38.5 m^2 = 0.5 × 38.5= 19.25 kg= 19 1/4 kg

Answer»

=> Radius of the circular flower bed = 3.5 m

=> Area of the circular flower bed = π × r^2= 22/7 × (3.5)^2= 22/7 × 12.25= 22 × 1.75= 38.5 m^2

=> Fertilizer required for 1 m^2 = 1/2 kg = 0.5 kg

=> Fertilizer required for 38.5 m^2 = 0.5 × 38.5= 19.25 kg= 19 1/4 kg
