Ankita Priyadarshani answered this

Diameter = 1.6 m

Radius = 1.6/2 = 0.8 m

Area of circle = 3.14 × 0.8 × 0.8

= 2.0096 m²

Cost for polishing 1 m² area = Rs 15

Cost for polishing 2.0096 m² area = 15 × 2.0096 = 30.14

Therefore, it will cost Rs 30.14 for polishing such circular table.

Mahi C Patel answered this

Diameter = 1.6 meter
Radius = 1.6/2 = 0.8 meter
Area of circle = 3.14 * 0.8 * 0.8
= 2.0096 square meter
Cost of polishing one square meter = Rs. 15
Cost of polishing 2.0096 square meter = Rs. 15 * 2.0096
= Rs. 30.14
Therefore, it costs Rs. 30.14 for polishing such circular table.

Fiza Sindhi answered this

Diameter = 1.6 m

Radius = 1.6/2 = 0.8 m

Area of circle = 3.14 ? 0.8 ? 0.8

= 2.0096 m2

Cost for polishing 1 m2?area = Rs 15

Cost for polishing 2.0096 m2?area = 15 ? 2.0096 = 30.14

Therefore, it will cost Rs 30.14 for polishing such circular table.
