The cost of building a fence around a circular field is ₹7,425 at the rate of ₹13.50 per foot. What is the area of the circular field? [Use $$\pi = \frac{22}{7}$$]
The cost of building a fence around a circular field is ₹7,425 at the rate of ₹13.50 per foot.
circumference of circular field = $$\frac{7425}{13.50}$$
$$2\times\pi\times radius\ =550$$
$$2\times\frac{22}{7}\times radius\ =550$$
$$\frac{44}{7}\times radius\ =550$$Area of the circular field = $$\pi\times\left(radius\right)^2$$
= $$\frac{22}{7}\times\left(87.5\right)^2$$
= $$\frac{22}{7}\times7656.25$$
= $$22\times1093.75$$
= 24062.5 $$ft^{2}$$
