Correct option is C
Given:
Right-angled triangle with sides = 8 cm, 4 cm, and 12 cm.
Formula Used:
For a right-angled triangle, the hypotenuse is the diameter of the circumcircle.
Radius of circumcircle =
Area of circumcircle = πr²
Solution:
Here, the longest side = 12 cm i.e. Hypotenuse.
So, Radius r = = 6 cm.
Area of circumcircle = π × (6)² = 36π cm².
