Verified Answer
How many plants (approximately) will be there in a circular bed whose ...
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.
