Question
If a triangle with base 4 cm has the same area as a
circle with radius 4 cm, then the corresponding altitude (in cm) of the triangle is:ÂSolution
Using formula Area of triangle = 1/2 x base x height and Area of circle = πr2, Let the corresponding altitude of the triangle = a cm. According to the question, Area of the triangle = Area of the circle ⇒ 1a/2 x 4 = π x 4 x 4 ⇒a = 2 x 4 π ⇒a = 8 π cm
