If the square of product of three sides of the triangle is 1024 units and the area of its circumcircle is 16π . What is the are of the given triangle? |
2 sq. units 3sq. units 2.5 sq. units 4sq. units |
2 sq. units |
We know that, R = \(\frac{ abc }{4Area}\) Area of circle = πr2 We have, The product of the three sides of the triangle = 1024 units Area of circle = πR2 16π = πR2 R = 4 (abc)2 = 1024 (abc) = 32 So, R = \(\frac{ abc }{4Area}\) = \(\frac{ 32 }{4Area}\) 4 = \(\frac{ 32 }{4Area}\) Area = 2 We know that, R = \(\frac{ abc }{4Area}\) Area of circle = πr2 We have, The product of the three sides of the triangle = 1024 units Area of circle = πR2 16π = πR2 R = 4 (abc)2 = 1024 (abc) = 32 So, R = \(\frac{ abc }{4Area}\) = \(\frac{ 32 }{4Area}\) 4 = \(\frac{ 32 }{4Area}\) A = 2 |
