Question

from a circular sheet of radius 4 centimetre a circle of radius 3 cm is removed find the area of remaining sheet take Paye 3.14

Answer 1

remaining area = 22 sq cm

Answer 2

radius of circular sheet = 4cm

area of sheet = πr^2

= 3.14 × 4 × 4
= 50.24cm^2

similarly,
area of smaller sheet = 3.14 × 3 × 3
= 28.26cm^2

area of remaining sheet = 50.24 - 28.26
= 21.98cm^2
