Open in App
Solution
Area of squre paper=25×25=625cm^2
area of circle with radius =1cm=pie×1×1=pie=3.14cm^2
area of 180 such circle=3.14×180=565.2
so remining area=625-565.2
=59.8 cm^2
area of circle with radius =1cm=pie×1×1=pie=3.14cm^2
area of 180 such circle=3.14×180=565.2
so remining area=625-565.2
=59.8 cm^2
