Detailed Solution
Download Solution PDFGiven:
The side of an equilateral triangle is 12 cm.
Formula used:
The formula for the inradius (r) of an equilateral triangle is r = (a√3)/6, where a is the length of a side of the equilateral triangle.
Calculation:
The side length of the equilateral triangle is given as 12 cm.
Using the formula for inradius, we get:
r = (a√3)/6
r = (12√3)/6
r = 2√3 cm
Therefore, the radius of the incircle of the equilateral triangle is 2√3 cm.
