Question 107

Find the total cost of wooden fencing around a circular garden of diameter 28 m. If 1 m of fencing costs Rs. 300.

Answer 1

Diameter of a circular garden = 28 m
$\therefore$ Radius of circular garden $=\frac{28}{2}\times 14m$
$\therefore$ Circumference of circular garden
$=2\pi r$
$=2\times \frac{22}{7}\times 14$
= 88 m
$\therefore$ Fencing cost of circular garden
$=88\times 300$
= Rs.26400
