Question
If a triangle with base 10 cm has the same area as a
circle with radius 10 cm, then the corresponding altitude (in cm) of the triangle is:ΒSolution
Using formula Area of triangle = 1/2 x base x height and Area of circle = Οr2, Let the corresponding altitude of the triangle = a cm. According to the question, Area of the triangle = Area of the circle β 1a/2 x 10 = Ο x 10 x 10 βa = 2 x 10 Ο βa = 20 Ο cm
