Question

Find the cost of polishing
​

Answer 1

Answer:

Rs. 34.636

Step-by-step explanation:

Diameter of the circular table top, d = 2.1 m

So, Radius, r will be = 2.1/2 = 1.05 m

Area of circle = π r^2

Therefore, area of the table top

= π (1.05)^2

= π × 1.1025

= 3.4636 m^2

Cost of polishing = Rs. 10/m^2

Therefore, cost of polishing the table top

= 3.4636 × 10

= Rs. 34.636
