Question

From a circular sheet of radius 8 cm, a circle of radius 3 cm and a square of

4 cm are removed .Find the area of the remaining sheet.(Taken π = 3.14)​

Answer 1

Answer:

The area of the circular sheet with 4cm radius is,

A=πr2

=16π

=16πThe area of the circular sheet with 3cm radius is,

A=πr2

=9π

=9πSince the circle with radius 3cm is removed, then the remaining area is,

=9πSince the circle with radius 3cm is removed, then the remaining area is,A=16π−9π

=9πSince the circle with radius 3cm is removed, then the remaining area is,A=16π−9π=7π

=9πSince the circle with radius 3cm is removed, then the remaining area is,A=16π−9π=7π=7×3.14

=9πSince the circle with radius 3cm is removed, then the remaining area is,A=16π−9π=7π=7×3.14=21.98cm2
