. plants will be there in a circular bed whose outer edge measures 30cm alowing 4cm2 (square) for each plant ?
Verified Answer
. plants will be there in a circular bed whose outer edge measures 30c...
The outer edge of the bed = circumference.
So, 2(pi)* radius = 30 cm
==> radius, r = 30 /(2 pi) = 4.77 cm
Now, area of the circular bed = (pi)*r^2 = 3.14 * (4.77)^2 = 71.44 square cm
No of plants = 71.44 / 4 = 17.86 say 17.
So, the answer is 17.

Calculating the number of plants in a circular bed
To calculate the number of plants that can fit in a circular bed with a 30cm outer edge, allowing 4cm² for each plant, we need to follow these steps:
1. Calculate the area of the circular bed:
- The area of a circle is calculated using the formula A = πr², where r is the radius of the circle.
- Since the outer edge of the circular bed is 30cm, the radius (r) would be half of that, which is 15cm.
- Substituting the values into the formula, we get A = π(15)² ≈ 706.86 cm².
2. Calculate the area of each plant:
- Each plant is allowed 4cm² of space.
3. Divide the area of the circular bed by the area of each plant:
- Divide the area of the circular bed by the area of each plant to find out how many plants can fit in the bed.
- 706.86 cm² ÷ 4 cm² ≈ 176.72 plants.
4. Answer:
- Therefore, approximately 176 plants can fit in the circular bed with a 30cm outer edge, allowing 4cm² for each plant.
