5. A circular grass lawn has a radius of 6 m. fertilizers is to be broadcast at the rate of 1 kg for every 25 square meters. If the fertilizers can be bought in 1-kg bags, how many bags must be bought? How much will it cost at P12 per kilogram?
Answers
Answer:
Bags = 4.52 bags , Cost of fertilization = 54.24 Rupees
Step-by-step explanation:
According to the information provided in the question it is given as
A circular grass lawn has a radius = 6 m.
fertilizers is to be broadcast at the rate of 1 kg for every 25 square meters.
If the fertilizers can be bought in 1-kg bags,
We need to find how many bags must be bought? How much will it cost at P 12 per kilogram?
First it is a circular grass land = Area of circle = Area of fertilization
[tex]A = \pi r^{2} \\ A = \frac{22}{7} \times 6\times 6\\ A = 3.142\times 36\\ A =113.11m^{2} [/tex]
As fertilize 1 kg for every 25 square meter
Than =113.11 fertilize = 113.11 /25
=4.52 kg
So this is the total kg required for fertilization
Hence total bags of 1 kg = 1 x 4.52
=4.52 bags
So total 4.52 bags required for fertilization
Per kg fertilization rate = 12 rs
Hence
Cost = 12 x 4.52
= 54.24 Rupees
