Question

QuesAn equilateral triangle of side 44 cm is formed using a wire. The same wire is used to make a circle. What will be the diameter of circle in cm?

a)  42

b)  44

c)   52

d)  54

Solution

Perimeter of equilateral triangle = 44*3 = 132
Circumference of Circle = Perimeter of Triangle 

2*Pi*r = 132
2*(22/7)*r =132
r = 21 cm
diameter = 21*2 
diameter = 42 cm
Ans =42cm
