Question

find the cost of polishing a circular table top of diameter 2.1 M if the rate of polishing is rupees 10 per metre square

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 = 2.1m. Hence, r = 1.05 m

Area = π r^2

= 3.14 × 1.05^2 = 3.46185 sq m

Cost of polishing = Rate × Area

= Rs 10 × 2.0096 = Rs 34.6185
