Question

from a circular sheet of radius 4cm,a circle of rafius 3vm is removed.find the area of the remaining sheet.takeπ=3.14

Answer 1

hiii!!!

here's ur answer...

given the radius of the circular sheet is 4cm.

area of the circular sheet = πr²

= 3.14×4×4

= 3.14×16

= 50.24cm²

given the radius of the circle which is removed from the circular sheet is 3cm.

area = πr²

= 3.14×3×3

= 3.14×9

= 28.26cm²

hence area of the remaining sheet = 50.24 - 28.26

= 21.98cm²

hope this helps..!

Answer 2

Area of circular sheet = πr^2
                                   = 3.14*4*4
                                   = 50.24cm^2
Area of circle removed = 3.14*3*3
                                     = 28.26cm^2
Area of remaining sheet = 50.24 - 28.26cm^2
                                       = 21.98cm^2
