    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: 
    A 8 π cm Correct Answer Incorrect Answer
    B 12 π cm Correct Answer Incorrect Answer
    C 10 π cm Correct Answer Incorrect Answer
    D 14 π cm Correct Answer Incorrect Answer

    Solution

    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
