Question

In a circular garden of 50 m radius , a pond is constructed in the form of a circle with radius 20 m . Find rhe area of the land left - out

Answer 1

In a circular garden ,radius= 50m
we know,
Area of circular garden =π r sq.
=3.14×50×50
=7850 sq.m
Now,
a pond is constructed in the form of a circle with radius 20m.
Area of the circular garden in which pond is constructed =πrsq.
= 3.14×20×20
= 1256 sq. m
therefore of the land left out= Area of the circular garden -area of the circular garden in which the pond is constructed.
=7850-1256
=6594 sq.m

Answer 2

area left is 6594m^2
