Answer 1

Answer:

Cost of cleaning the field = ₹3257.1

Step-by-step explanation:

Given:-

$\frac{Diameter }{2}$Diameter of the circle = 42 m

Cost of cleaning per m² = ₹2.35

formula used

area of a circle = $\pi$$r^{2}$

where,

r = Radius

$\pi$ = $\frac{22}{7}$

Radius = $\frac{Diameter}{2}$

           =>$\frac{42}{2}$

Radius = 21

According to the question by using the formula of Area of a Circle, we get,

Area of circular field = ( $\pi$ *  $21^{2}$) $m^{2}$
