Question

Cost of plougng at the rate of Rs10 per meter squre is Rs 1540 . Find the radius of circler field

Answer 1

Hi friend
----------------
Your answer
---------------------

Cost of ploughing = Rs 1540

Rate of ploughing = Rs 10/m²

Then,
----------

Area of the field = 1540/10 m² = 154m²

Now,
---------

The field is circular in shape.

So,
------

π × (r)² = 154

=> 22/7 × r² = 154

=> r² = (154 × 7)/22

=> r² = 49

=> r = √49

=> r = 7 cm
