Question

Find the cost of polishing a circular tabletop of diameter 1.6m,if the rate of polishing is ₹15/m² take (×=3.14)

Answer 1

Answer:

Namaste here is your answer mate!

The cost of polishing a circular tabletop is ₹30.144

Step-by-step explanation:

First we have to find radius.

So,

Radius = Diameter/2 = 0.8

Now,

Area = πr²

= 3.14 × 0.64 m²

= 2.0096 m²

The cost of polishing a circular tabletop

= ₹15/m² × 2.0096 m²

= ₹30.144

Answer 2

Answer:

ans is rs 30.144

Step-by-step explanation:

Diameter = 1.6 m

Radius = 0.8m

area of circular table = πr² = 3.14 x 0.8 x 0.8 = 2.0096 m²

cost of polishing per m² = Rs 15

cost of polishing for 2.0096m² = 2.0096 x 15 = 30.144
