Steps of Construction:
1.Construct ΔDSP of given dimensions.
2.Draw perpendicular bisectors of two sides, DS and SP.
3.Denote the point of intersection as O.
4.Draw a circle with O as center and OD as radius.
As we know that for an equilateral triangle, the incenter is same as the circumcenter.
5.Taking O as center, and the OM as the radius draw a circle.
Circumradius = OP = 4.3cm
Inradius = OM = 2.1cm
For an equilateral triangle, Circumradius = 2×Inradius.
