A piece of wire is in the form of a rectangle whose length and breadth are 40 cm and 26 cm respectively. It is rebent in the form of a circle. Find the radius of the circle.

Answer 1

Answer:

21 cm

Step-by-step explanation:

Given dimensions are:

Length of rectangle = 40 cm.

Breadth of rectangle = 26 cm.

Area of rectangle = Length * Breadth

                              = 40 * 26

                              = 1040.

Perimeter of rectangle = 2(l + b)

                                      = 2(40 + 26)

                                      = 132 cm.

∴Circumference of circle = 132 cm.

Let the radius of the circle be 'r' cm.

∴ 2πr = 132

⇒ 2 * 22/7 * r = 132

⇒ 44r = 924

⇒ r = 21.

∴ Radius of circle = 21 cm.

Therefore, Area of circle = 21 cm.
