Question

A circular flower bed is of radius 3.5 m. If ½ kg of the fertilizer is required for 1 square metre area, how much fertilizer will be required for the flower bed?

Answer 1

Answer:

19.25kg will be required for the flower bed.

Step-by-step explanation:

=> Radius of the circular flower bed = 3.5 m

=> Area of the circular flower bed = π × r^2

= 22/7 × (3.5)

= 22/7 × 12.25

= 22 × 1.75

= 38.5m

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

=> Fertilizer required for 38.5m = 0.5 × 38.5

= 19.25 kg
