As we know from the current school curriculum in geometry, the diameter of the circle described around a right-angled triangle will be the hypotenuse.
That is, its radius will be equal to 1/2 of the hypotenuse.
We determine with the help of how many centimeters we can represent the radius of the circle described around our triangle, when from the condition of the task we know that its first leg is three centimeters, while the second is four centimeters:
√ (3 ^ 2 + 4 ^ 2): 2 = √25: 2 = 2.5.
Answer: 2.5 cm.
