Answer:

The total cost of polishing the given circular top of the table =Rs. 30.14

Step-by-step explanation:

Given:-

a circular table-top of diameter 1.6 m, if the rate of polishing is rs. 15/m2, take pi=3.14

To find:-

find a cost of a table polishing of a circular table-top.

Solution:-

Diameter of the circular table =d=1.6m

Radius=Diameter/2

Radius =1.6/2=0.8m

Radius of the circular table=0.8m

Area of the circle=πr² sq. units

Area of the circular table=π(0.8)²

=>A=3.14×0.8×0.8m²

=>A=2.0096

Cost of the polishing the table top per =Rs. 15

Cost of the polishing the table top per 2.0096

=>2.0096×15

=>30.144

=>Rs. 30.14

Answer:-

The total cost of polishing the given circular top of the table =Rs. 30.14

Answer:

Diameter = 1.6 m

∴ Radius = 1.62 = 0.8 m

Area of the table-top = πr square

= 3.14 × 0.8 × 0.8 m square

= 2.0096 m square

∴ Cost of polishing = ₹ 15 × 2.0096

= ₹ 30.14 (approx.)
