Question

its diameter.
Find the cost of polishing a circular table-top of diameter 1.6 m, if
the rate of polishing is 3 15/m_. (Take 1=3.14) 9-1-6 = 24
cm and bent it into the shape of a circle.​

Answer 1

Answer:

30.14m is the cost

Step-by-step explanation:

Given diameter of table (circular) =1.6m

radius =0.8m

radius =0.8marea of circle = πr

radius =0.8marea of circle = πr 2

radius =0.8marea of circle = πr 2 =3.14×0.64=2.0096m

radius =0.8marea of circle = πr 2 =3.14×0.64=2.0096m 2

radius =0.8marea of circle = πr 2 =3.14×0.64=2.0096m 2

radius =0.8marea of circle = πr 2 =3.14×0.64=2.0096m 2 Now rate of polishing per meter square =15Rs

radius =0.8marea of circle = πr 2 =3.14×0.64=2.0096m 2 Now rate of polishing per meter square =15RsCost of polishing table top = 15×2.0096

Cost = 30.14 m
