Find the apothem of an equilateral triangle with radius 8 cm.

In this question , the triangle is equilateral triangle , with radius equals to 8 cm  and we have to find the length of apotherm, a .

Using sine ratio rule,

For triangle ODC, opposite is a cm and hypotenuse is of length 8 cm .

So we will get

Multiplying both sides by 8

So the length of the apothem is 4 cm .
