Question

1. The area of shaded region between a square of side 14cm and the circle touching all sides of the square is
​

Answer 1

Answer:

42cm²

Step-by-step explanation:

Area of the square= 14²= 196cm²

Diameter of the circle = side of the square= 14cm

Radius of the circle = 14/2=7

Area of the circle= πr²= 22/7*7*7= 22*7=154

Area of the shaded region= Area of the square-Area of the circle= 196-154cm²= 42cm²

Answer 2

Answer:

...Hope you understand.....

Step-by-step explanation:

Side of a square =14cm

Draw a segment EF passing through center O

We can see,

⇒ AB=EF

And AB=14cm

∴ EF=14cm

EF is a diameter of a circle.

OF=r= 14= 7cm

2

⇒ Area of a circle =πr^2

=22×7×7

7

=154cm^2

⇒ Area of a square =(Side)^2

=(14)^2

=196cm^2

⇒ Area of shaded region = Area of square − Area of circle

=(196−154)cm^2

=42cm^2
