Question:

The lengths of two sides forming the right angle of a rightangled triangle are 18 cm and 24 cm.  What is the radius of the circle circumscribing the triangle?

Options:

30

15

12

9

Correct Answer:

15

Explanation:

Using triplet = 6 (3, 4, 5) =18, 24, 30

Diameter (AC)= 30 cm

So, Circum-radius = \(\frac{AC}{2}\) = \(\frac{30}{2}\) = 15 cm
