  1. 6 √3

    Step-by-step explanation:

    Length of a side of an equilateral triangle inscribed in a circle =



    where r is the radius of the circle

    Therefore, Area =









  2. Let the third side of triangle be x

    Now parameter of triangle = sum of its sides




  3.   27√3 in² ≈ 46.765 in²

    Step-by-step explanation:

    There are several ways you can go at this. One is to recognize that the triangle formed by two vertices and the circle center is an isosceles triangle with apex angle 120°. Its area will be

      A = (1/2)·r²·sin(120°) = (1/2)·(6 in)²·(√3)/2 = 9√3 in²

    The total area of the inscribed triangle is the area of 3 of these, so is ...

      A = 3·9√3 in² = 27√3 in²


    Alternate solution

    If we call the center of the circle point O, and the vertices of the inscribed equilateral triangle A, B, and C, we can define point X on segment AB such that OX⊥AB.

    Triangle AOX is a 30°-60°-90° triangle, so has sides in the ratios 1 : √3 : 2. That is, AO is twice the length of OX, and AX is √3 times the length OX.

    This makes OX = 3, AX = XB = 3√3, and XC = OX+OC = 3+6 = 9.

    Now we have the dimensions of triangle ABC: the base AB is 6√3, and the height (XC) is 9. The area can be found in the usual way:

      A = 1/2·bh = 1/2·(6√3 in)·(9 in) = 27√3 in²

  4. Third side:4a-3b

    Step-by-step explanation:

    We know that perimeter of a triangle is sum of all three sides,i. e. x,y and z

    Here in the question



    and z=?






    is the third side of the triangle.

    Hope it helps you.
