In a right-angled triangle abc, the angle is C = 90. hypotenuse AB = 30. Find the radius of a circle circumscribed about a triangle.
If a circle is circumscribed around a right-angled triangle, then the center of such a circle coincides with the middle of the hypotenuse of the triangle, and the radius of the circle is half the length of the hypotenuse.
R = AB / 2 = 30/2 = 15 cm.
Answer: The radius of the circumscribed circle is 15 cm.
