circular table top whose radius
is 30 m, if the rate of polishing
is Rs 10 per m2​

Answer 1

Answer:

28285.7

Step-by-step explanation:

Area of circle : π r^2

= 22/7 * 30 * 30

= 2828.57m^2

1m^2 polishing cost is Rs10

So, 2828.57m^2 polishing cost will be: 10* 2828.57 = 28285.7

Hence Rs. 28285.7 is the rate of polishing the table.
