Correct Answer: 7.5 cm
Solution : Sides 9 cm, 12 cm, and 15 cm, form a right triangle since 9 cm, 12 cm, and 15 cm is a Pythagorean triples. In a right-angled triangle radius of the circumcircle is half of the hypotenuse. So, the length of the radius of circumference = $\frac{15}{2}$ = 7.5 cm Hence, the correct answer is 7.5 cm.
