A wire of length 20 cm. is turned to form a
1) square of side 5 cm.
2) circle of radius 20/ (2*pi)= 10/pi

Ratio = 5/ (10/pi) = pi/2=3.14/2= 1.57

option 4.

perimeter of square is 20 so side is 5. Also 2(3.14)r = 20 so r =10/3.14. so ratio is 5:10/3.14. ie 15.7:10 .iie 1.57:1

Given, 4x = 2Πy (= 20), where x is side of square and y is radius of circle.
So, x/y = 2Π/4 = Π/2 = 3.14/2 = 1.57

side = 5

radius = 20 / 2 pi

ratio = 5 : (20/2pi) = pi/2 = 1.57

(20/4)/ (20/2*Π) = Π/2= 1.57

neena 15 years AGO

length of the wire = circumference of the circle=perimeter of the square=20 cm
(circumference) 20 = 2*3.14*r
r=3.18
Perimeter = 20 = 4*side
side=20/4=5
ratio of side to radius = 5 : 3.14
+1.57

Maths Quotes

Mathematics is like a rain... When we know how to solve it, We will continouosly do it.

Syawal

Pure mathematics is the world's best game. It is more absorbing than chess, more of a gamble than poker, and lasts longer than Monopoly. It's free. It can be played anywhere - Archimedes did it in a bathtub.
