Answer:₹34.65
Step-by-step explanation:
Because diameter is 2.1m radius is 2.1/2m
We know area of a circle is πr^2.
So here area =22×2.1×2.1/7×2×2
=11×0.3×2.1/2
Cost= 10×11×0.3×2.1/2
=₹34.65

Diameter of the circular table top = 2.1 m
\Radius of the circular table top =2.1/2=1.05
Area of circular table top = π r 2
= 3.14 x 1.05 x 1.05= 3.461 m2
Now cost of 1 m2 polishing = Rs 10
Then cost of 3.461 m2 polishing = 10x 3.461= Rs 0.3461 (approx.) Thus, the cost of polishing a circular table top is Rs 0.3461 (approx.)
