Question

The diameter of a circular plot of ground is 28m.Find the cost of levelling the ground at the rate of rupees 3 per. Sq.
M

Answer 1

Diameter of the plot =28m

Radius of the plot = 28/2 = 14m

Area of the plot =$\pi r^{2}$

                          = 22/7 x 14 x 14

                          = 610

Cost of levelling = rs.3per sq.

Total cost of levelling =3 x610

                                  = Rs.1830

                         

Answer 2

Answer:

Rs.1848

Explanation:

d=28m

then r= 14 m

area =πr*r

=3.14*14*14

=616 sq.m

cost at 3 rs = 3*616

= rs.1848
