How many plants will be there in a circular bed whose outer edge measure 30 cms, allowing 4 cm2 for each plant ? Choose the most appropriate option:
A) 18
B) 750
C) 24
D) 120
E) None of these
Circumference of circular bed = 30 cm   18rea of circular bed = (30)2⁄4π   Space for each plant = 4 cm2   ∴ Required number of plants   = (30)2⁄4π ÷ 4 = 17.89 = 18(approx)   18nswer 18
