Question

From a circular sheet of radius 4cm a circle of radius 3cm is removed. Find the area of the remaining sheet .(Take π=3.14)

Answer 1

Answer:

21.98 cm2

Step-by-step explanation:

Area of big circle= πR^2= 16π

Area of small circle= πr^2= 9π

Area of remaining sheet

= Area of big circle - Area of small circle

=16π-9π

=7π

=7 x 3.14

= 21.98 cm2

Answer 2

Answer:

21.98 cm^2

Step-by-step explanation:

Area of remaining sheet = area of initial sheet - area of removed sheet

3.14×4^2 - 3.14×3^2

3.14( 16 - 9 )

3.14×7

21.98cm^2
