Question

fifrom a circular sheet of radius 10cm a circle of radius 4cm is removed find the area of the remaining sheet​

Answer 1

Answer:

264

Step-by-step explanation:

area of circle= πr^2

area of bigger circle= π× 10×10

area of smaller circle= π×4 ×4

.

. . area of remaining circle= π× 10×10 - π×4 ×4

= π{ 100-16}

= 22/7 × 84

= 22× 12

264

Answer 2

Answer:

Area of remaining sheet is 264sq.cm.

Step-by-step explanation:

Given that

Radius of circular sheet is 10cm

Radius of circle is 4cm

To find

Area of remaining sheet

Solution

As per given statement area of circle is removed by area of circular sheet

as

$area \: of \: circular \: sheet = \pi \times {10}^{2}$

$area \: of \: circular \: sheet = 3.14 \times 100 \\ = 314.159 {cm}^{2}$

now

$area \: of \: circle = \pi \times {4}^{2}$

$area \: of \: circle = 3.14 \times {4}^{2} \\ =50.24 {cm}^{2}$

now

$area \: of \: remaining \: sheet = 314.159 - 50.24$

hence by subtraction

$area \: of \: remaining \: sheet = 264 {cm}^{2}$
