find a cost of a table polishing of a circular table-top of diameter 1.6 m, if the rate of polishing is rs. 15/m2, take pi=3.14
Answers
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 m²
=>A=3.14×0.8×0.8m²
=>A=2.0096 m²
Cost of the polishing the table top per m²=Rs. 15
Cost of the polishing the table top per 2.0096 m²
=>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.)
