As given in the figure, in the rectangular paper ABCD ,AB=30 cm and BC=20 cm. a semicircle with diameter BC is cut off from the paper. then the area of the remaining paper shown as ruled is ...... cm square ( pie =3.14) A.543B.443C.286D.246 |
|
Answer» Since BC is the diameter, so radius = d/2 = 20/2 = 10 cmRadius = 10 cmArea of the semicircular portion = 1/2πr²= 1/2*3.14*100Area of the semicircular portion = 157 sq cmArea of the rectangle ABCD = L*B= 20*30Area of the rectangle ABCD = 600 sq cmNow area of the remaining part of the paper = Area of the rectangle ABCD - Area of the semicircular portion= 600 - 157= 443 sq cm |

cleThe tangent lines to the circle x2 + y2-6x + 4y = 12 which are parallel to the line 4x + 3y + 5-0 aregiven by(A) 4x+3y-7 0, 4x 3y+ 15 0(C) 4x +3y-17 0, 4x +3y 13 0(B) 4x + 3y-31:0, 4x + 3y + 19:0(D) 4x + 3y-31 0, 4x+3y-19 0 |
|
Answer» Let Equation of line parallel to 4x + 3y +5 =0 will be 4x + 3y + λ= 0.So, the distance of the line from the centre of the circle(3,-2) should be equal to radius 5.So, |4*3 + 3*(-2) + λ| / (4²+3²) = 5hence, 6+λ= 25 or -25λ = 25-6 or -25-6λ= 19 or -31So, equation will be 4x + 3y +19=0 or 4x + 3y -31=0. |
