Question

from a circular sheet of radius 5cm , a circle of radius 4 cm is removed . find the area of remaining sheet​

Answer 1

Step-by-step explanation:

radius=5 cm

means side= 5cm

4cm is removed means 1 cm is left

area of sheet =1cm^2

Answer 2

Step-by-step explanation:

area of circular sheet = A=πr2

= 3.14×5cm×5cm

=78.5cm^2

area of circle = πr2

=3.14×4×4

=50.24cm^2

now ,

the area of reaming sheet=78.5-50.24=28.26cm
