area of circular field with diameter 40 CM
r=20cm
area=pir^2
=22/7 ×20×20
1257.14..approx.
then area of circular field with diameter 96 cm
r=48cm
area=pir^2
=22/7×48×48
7241.14cm^2
then the area of the field whose area is equal to the sum of the area of the given to field is
8498.28cm^2=22/7×r^2
r=52cm
d=104cm
r=20cm
area=pir^2
=22/7 ×20×20
1257.14..approx.
then area of circular field with diameter 96 cm
r=48cm
area=pir^2
=22/7×48×48
7241.14cm^2
then the area of the field whose area is equal to the sum of the area of the given to field is
8498.28cm^2=22/7×r^2
r=52cm
d=104cm
