Question

Find the area of the biggest circle that can be drawn within a square of perimete<br />28 cm. [Hint:π=22/7]​

Answer 1

Step-by-step explanation:

side of square is 28cm

then the dia of circle is 28cm

and radias is 14cm

Area of square is

\pi{r}^{2}πr

2

then

\pi {14}^{2}π14

2

196*22/7=28*22

=616

Answer 2

Solution:-

To Find:  Area of biggest circle

Given:  Side of square(Diameter) = 28 cm

Finding the radius,

Radius = Diameter/2

Radius = 28/2

Radius = 14 cm

• Therefore,The radius of circle is 14 cm.

Now,finding the area of biggest circle,

Area of circle = πr²

Where,

• π = 22/7
• r = 14

Area of circle = 22/7 × 14²

Area of circle = 22/7 × 14 × 14

Cancelling the 7 with 14

Area of circle = 22 × 2 × 14

Area of circle = 44 × 14

Area of circle = 616 cm²

Hence,

• The area of biggest circle is 616 cm².
