Question

find the cost of polished a circular table top of of diameter 3.2 if the rail of polished rs 301 m square. table pye =3.14​

Answer 1

To calculate the cost of polishing of circular table, we have to calculate its area first of all.Here, Given diameter of the circular table-top = 1.6 m. Hence, r = 0.8 m

Area = π r2

= 3.14 × 0.8 × 0.8 = 2.0096 sq m

Cost of polishing = Rate × Area

= Rs 15 × 2.0096 = Rs 30.144
