Find the length of circumradius of a right-angled triangle whose adjacent sides are 3cm and 4cm?
As per the question we have to find out the length of circumradius of a right-angled triangle whose adjacent sides are 3cm and 4cm.
Let BAC be a triangle where AB = 3 cm and AC = 4cm.
We draw the perpendicular bisector of AB and BC as RS and PQ respectively.
AR = 32=1.5 cm
RO = 42=2 cm
The length of the circumradius is equal to AO.
By Pythagoras theorem
On substituting the values we get:
Hence, the circumradius of the triangle is 2.5 cm.
