Question

hey Bhaiya is in the shape of the of a rectangle of length 36 cm and width at is 30 centimetre is received and bent in the form of a circle find the radius of the circle

Answer 1

Given

Length =36cm
Width =30cm 
Perimeter of rectangle =2(l+b)

=2(36+30)

=2x66

=132cm

The same wire reshaped in circle now so 

Perimeter of rectangle = Circumference of the circle 

Circumference of circle = 2 pi r 

132= 2 pi r

132=2 x 22/7 x r

R=132x7/2x22

R= 21cm

This is ur ans hope it will help you

Answer 2

Hola Friend ✋✋✋

Length of the rectangle = 36 cm

Breadth of the rectangle = 30 cm

Let the radius of the circle be ' r '


Perimeter of rectangle = circumference of circle

2 × ( 36 + 30 ) = 2 × π × r

$r = \frac{66 \times 7}{22}$


$= 21cm$



Hope it helps
