Question

a circular well with radius 17.5 m has been dug in a corner of field. The field is 80m and 50m wide. Find the area of remaining field

Answer 1

Area of Remaining Field= Area of Whole Field-Area Of Cirlce(Well)
Area Of Whole Field= 80×50=4000 $m^2$
Area Of Circle(Well)=22/7×17.5×17.5=962.5 $m^2$

Hence,
Area Of Remaining Field= 4000-962.5= 3037.5 $m^2$
