The radius of the circle passing through the vertices of a triangle with sides 6 cm, 8 cm, and 10 cm is:
Show answer & explanation
Correct answer: A
Explanation
Given:
Sides of the triangle = 6 cm, 8 cm, 10 cm
Formula:
Radius of the circumcircle of a right-angled triangle = Hypotenuse / 2
6² + 8² = 36 + 64 = 100 = 10²
Therefore, the triangle is right-angled and the hypotenuse = 10 cm
Radius = 10 / 2 = 5 cm
