An equilateral
△ inscribed in a circle, the altitudes of from each vertex meets at a common point
O. The distance from the tip of the vertex to the point
O is the radius of the circle
Here,
For easy calculation, let take the radius = 2 ( it can be any value)
MO = radius of the circle = 2
since, MNP is equilateral
△so,
∠ OMP = 30
∠ OBM = 90
∠ MOB = 60
Hence, the
△ MOB is a 30:60:90 triangle and the sides are divided in the ratio as 1 :
√3 : 2
We know, OM = 2
therefore, MB =
√3and OB = 2
Now,
area of the circle =
π∗22 =
4πArea of the equilateral △=
