DIRECTION for the question:Solve the following question and mark the best possible option.
A boy constructed two figures, an equilateral triangle and a semicircle such that the side of an equilateral triangle and the radius of the semicircle are equal. What is the ratio of perimeter of the equilateral triangle to the perimeter of the semicircle?
A)
3 : 2Ï€
B)
3 : π
C)
3 : (1 + π)
D)
3 : (2 + π)
E)
2 : (3 + π)
D
Let the side=radius = 1
Perimeter of equilateral triangle = 3
Perimeter of semicircle = Diameter + Lenght of curve (πr) = 2 + π
Required ratio = 3/(2+Ï€)
