Question

a circle of radius of 2 cm is cut from a square sheet of paper of side 8 cm find the area of the remaining sheet (use π = 3.14​

Answer 1

Answer:

Area of the remaining sheet is 51.44 $cm^2$

Step-by-step explanation:

The area of a circle with a radius $r$ is,

$Area = \pi r^2$

So the area of the circle of radius 2cm is,

$Area =\pi \times 2^2=4\pi=12.56$ $cm^2$

Area of a square with side measurement $a$ is,

$Area= a^2$

When the side of the square is 8cm, the area is,

$Area= 8^2 =64\ cm^2$

The area of the remaining sheet is given by,

$Area \ of\ square - Area \ of\ circle = 64-12.56=51.44$ $cm^2$

Answer 2

Answer:

Area of the remaining sheet $= area\ of\ square\ sheet\ -\ area\ of\ circle$.

Step-by-step explanation:

Area of the square sheet $=a^{2}$ , where $a$ is the side of the square.

area of square $=8^{2} =64cm^{2}$

Area of circle $=\pi r^{2}$, where $r$ is the radius of the circle.

                      $=3.14(2^{2} )$

                      $=12.56$$cm^{2}$

therefore area of the remaining sheet $=64-12.56=51.44cm^{2}$.

Hence the answer
