Question

A rectangle have length 5cm and breadth 2cm is deformed to make circle then find the area of circle ? please give step by step answer​

Answer 1

Length of the rectangle= 5 cm

Breadth of the rectangle=2 cm

We know,

Area of rectangle=length x breadth=5x2=10 cmsq.

Since,

The circle is formed by deforming the rectangle.

Therefore,

Area. of rectangle=Area of circle=10 cmsq.

Therefore,

The area of the circle is 10 cmsq.

Hope This Helps..Thank You...

Answer 2

step by step explanation

perimeter of the rectangle= l×2 + b×2

5×2+2×2 = 14

if the perimeter is 14 cm

then the circumference = 14

formula of circumference of a circle

2πr = 14

2 × 3.14× r = 14

6.28 × r = 14

r = 1400÷628

r = 2.22

area of a circle = πr^2

3.14×2.22^2

3.14 × 4.92

15.44

the area of the circle= 5.44

I can Just hope that this is the correct answer if not please correct it thank you
