Question
If a triangle with base 7 cm has the same area as a
circle with radius 7 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 7 = π x 7 x 7 ⇒a = 2 x 7 π ⇒a = 14 π cm
