Question

a circle of radius 3 cm is cut out from a circular sheet of radius 5 cm. find the area of the remaining shwet.​

Answer 1

circle radios 5 cm

area of this circle = πr^

=22/7 ×5×5

=22/7×25

=550/7

circle radios 3 cm

area of this circle=πr^

=22/7×3×3

=22/7×9

= 198/7

area of remaining sheet =550/7-198/7

=352/7

=50.2cm^
