Answer 2

Answer:

The question mentions about polishing the table which means we must find the area  of circle

Lets convert 8cm to m by dividing it by 100 , therefore 8 cm =0.08m

Area of circle=$\pi r^{2}$

where r = 0.08 m

=3.14*0.08*0.08=0.020096m2

cost = area*cost per m2

=0.020096*15=0.30144 rupees
