Find the cost of polishing a circulare fable top
of diameter 1.6m if the rate of polithing is 15/m2​

Answer 1

Answer:

Diameter of the circular table top = 1.6 m

\Radius of the circular table top =1.6/2 =0.8

Area of circular table top = π r 2

= 3.14 x 0.8 x 0.8 = 2.0096 m2

Now cost of 1 m2 polishing = Rs 15

Then cost of 2.0096 m2 polishing = 15 x 2.0096 = Rs 30.14 (approx.) Thus, the cost of polishing a circular table top is Rs 30.14 (approx.)

this is the answer for the question
