Question

a piece of wire is in the form of a rectangle whose length is 52 centimetre and breadth is 36 cm It is cut at a point and bent in the form of a circle find the radius of the circle​

Answer 1

Length of circle= 52cm
Breadth= 36 cm
Perimeter (Length of wire) = 2(52+36) cm
=176cm

Since, Circumference of circle = Length of wire
= 》2×pi×r = 176cm
》2×(22/7)×radius =176 cm
》44/7 × radius =176 cm
》Radius = (176)(7/44)
Therefore, Radius= 28 cm Ans.
Hope it helps.

Answer 2

SOLUTION

Given,

Dimension of rectangle are 52cm&36cm

so, perimeter of rectangle= 2(l+b)

=) 2(52+36)

=) (2× 88)cm

=) 176cm

Now the given rectangular piece is bent in the form of a circle.

Therefore, circumference of circle=2πr

=) 2πr= 176cm

=) 2× 22/7× r= 176cm

=) r= 4×7= 28

=) 28cm is the radius of the circle

hope it helps ☺️⬆️
