Question

 A wire is in the shape of a rectangle with length 10cm and bredth 7cm which is bent to form a circle. What will be the circumference of the circle ? ​

Answer 1

Answer:

circumference = 18

Step-by-step explanation:

Length of rectangle = 5 cm

Breadth of rectangle = 4 cm

We know that the perimeter of rectangle :

Perimeter of rectangle = 2(Length + Breadth)

Perimeter of rectangle = 2(5 + 4)

Perimeter of rectangle = 18 cm

As the circle is made by same wire so the circumference of the circle would be same as perimeter of rectangle .

The circumference of Circle = 18 cm

Answer 2

Answer: 34 cm

Step-by-step explanation:

the rectangle and circle are made of the same lenght of wire so we just need to find the perimeter of the rectangle the fourmulae of rectangle = 2(l + b) so l = 10 & b = 7 so the formulae = 2( 10 + 7 )

2 ( 10 + 7 )

2 ( 17 )

2 * 17

34
