Question

10. How many plants can be planted in a circular garden of circumference 26.40 m if a space
of 600 cm is to be allowed for each plant?
​

Answer 1

$\red{\textbf{Answer :- 9}}$

Step-by-step explanation:

$\red{\textbf{Given}}$

$Circumference \: of \: circle  \: =26.40 m$

$2\pi r = 26.40$

$2 \times \Large\frac{22}{7} \times r = 26.40$

$r = \Large \frac{26.40 \times 7}{2 \times 22}$

$r = 4.2m$

$Area \: of \: circluar \: garden \:  =\pi {r}^{2}$

$\Large\frac{22}{7} \times {4.2}^{2}$

$= 55.44 {m}^{2}$

$Area \: of \: each \: plant =600 {cm}^{2} = 6 {m}^{2}$

$No. \: of \: plants \: can \: planted = \: \Large \frac{55.44}{6}$

$= 9.24$

≈ 9

$\red{\textbf{Thus, 9 plants can be planted . }}$
