    GIVEN :
    x + y = 8
    xy = 15.

    we know that,

    {tex}( x+y )^2 = x^2 + y^2 + 2xy{/tex}
    {tex}x^2 + y^2 = ( x + y )^2 - 2xy{/tex}
    {tex}= 8^2 - 2×15{/tex}
    = 64 - 30
    {tex}x^2 + y^2 = 34.{/tex}

    Given: In quadrilateral ABCD, AB smallest & CD is longest sides. To Prove: ∠A>∠C & ∠B>∠D Construction: Join AC. Mark the angles as shown in the figure.. Proof: In △ABC , AB is the shortest side. BC > AB ∠2>∠4 …(i) [Angle opposite to longer side is greater] In △ADC , CD is the longest side CD > AD ∠1>∠3 …(ii) [Angle opposite to longer side is greater] Adding (i) and (ii), we have ∠2+∠1>∠4+∠3 ⇒∠A>∠C Similarly, by joining BD, we can prove that ∠B>∠D

    1000lt = 1 meter*3
    15.4 lt = 0.0154 m*3
      volume of cylindrical vessel = pi . r*2h
     r   =  0.07 m

     surface area of cylindrical vessel open at the top = curved surface area of cylinder + area of base
     = 2pi . r . h + pi . r2
     = pi . r ( 2h + r )
     = 22/7x0.07 ( 2x1 + 0.07 )
    surface area     = 0.4554 m2  =4554cm2
      cost of 100 cm2​ of metal sheet = Rs. 25
      cost of 1 cm2 of metal sheet     = Rs. 25/100
     cost of 4554 cm2 of metal sheet
    = Rs. 25 ×4554 / 100
    = Rs. 1138.5
