The correct Answer is:
To find the radius of an equilateral triangle given its circumradius, we can use the relationship between the circumradius (R) and the radius (r) of the triangle. ### Step-by-Step Solution: 1. **Understand the relationship between circumradius and radius**: For an equilateral triangle, the relationship between the circumradius (R) and the radius (r) is given by the formula: \[ r = \frac{R}{3} \] where R is the circumradius. 2. **Substitute the given circumradius**: We are given that the circumradius \( R = 4\sqrt{3} \) cm. We will substitute this value into the formula: \[ r = \frac{4\sqrt{3}}{3} \] 3. **Calculate the radius**: Now, we perform the division: \[ r = \frac{4\sqrt{3}}{3} \text{ cm} \] 4. **Final answer**: Therefore, the radius of the equilateral triangle is: \[ r = \frac{4\sqrt{3}}{3} \text{ cm} \]
