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

Answer 1

Answer:

3.14×(4²-3²)

3.14×(16-9)

3.14×7

21.98cm²

Answer 2

Answer:

${\qquad{\sf{ Myself{\small_{(Other Best User) }} \downarrow }}}$

Step-by-step explanation:

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

A=πr2

• =16π

The area of the circular sheet with 3cm radius is,

A=πr2

=9π

Since the circle with radius 3cm is removed, then the remaining area is,

${\qquad{\sf{\longmapsto A=16π−9π}}}$

${\qquad{\sf{\longmapsto =7π}}}$

${\qquad{\sf{\longmapsto =7×\tt\large\underline\green{3.14}}}}$

${\qquad{\sf{\longmapsto =21.98cm^2\: \: \: \: \mapsto\tt\large\underline\green{ :)}}}}$
