Correct answer: B. 2.5 unit2.5 इकाई
Explanation
The line 4x + 3y = 12 meets the axes at (3, 0) and (0, 4), so with the origin the triangle has legs 3 and 4 and a right angle at O. Its hypotenuse is √(3² + 4²) = 5, and for a right triangle the circumcircle has the hypotenuse as diameter. Hence the radius is 5 ÷ 2 = 2.5 unit.रेखा 4x + 3y = 12 अक्षों को (3, 0) तथा (0, 4) पर काटती है, अतः मूलबिन्दु के साथ बनने वाले त्रिभुज की भुजाएँ 3 और 4 हैं और O पर समकोण है। कर्ण = √(3² + 4²) = 5, तथा समकोण त्रिभुज में कर्ण ही परिवृत्त का व्यास होता है। अतः त्रिज्या 5 ÷ 2 = 2.5 इकाई है।More Mathematics & Numerical Ability questions
