Question

Find the circumradius of a right angled triangle, the hypotenuse of which is 12 cm and the length of any other side is 5 cm.

• A. 5 cm
• B. 4 cm
• C. 6 cm
• D. 8 cm

Answer 1

The correct option is C

6 cm

Given that

The hypotenuse of a right angles triangle is 12 cm.

The circumcenter of a right angles triangle lies on the midpoint of the hypotenuse and the circumradius is equal to half of the length of the hypotenuse.

Therefore, circumradius of the right-angled triangle the length of whose hypotenuse is 12 cm = $\frac{12}{2}=6$ cm
