Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

sin 36.87 = 3\/5<\/p>\n

Area of the triangle = 1\/2 * 10 * 10 * sin(36.87) = 50*3\/5 = 30<\/p>\n

Area of the sector = 36.87\/360 * 22\/7 * 10 * 10 = 32.18<\/p>\n

So, the area of the minor segment = 2.18 $cm^2$<\/p>\n

2)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

The angle subtended by the arc AB at the center of the circle is 60 degrees. The circumference of the circle is 2*22\/7*14 = 88 cm
\nSo, the length of the arc is 60\/360 * 88 cm = 88\/6 cm = 44\/3 cm<\/p>\n

3)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let the angle subteded by the first arc at the center be a, the angle subtended by the second arc at the center be (a+d) and so on.<\/p>\n

So sum of the 8 arcs = n\/2 * ( 2a + (n-1) d)=360\u00b0 where n=8<\/p>\n

So, 4(2a+7d) = 360 => 2a + 7d = 90<\/p>\n

Also, angle subtended by HA at the center = a + 7d = 70<\/p>\n

So, a = 20 and d = 50\/7<\/p>\n

Angle subtended by the arc EF at the center = a+4d = 20+200\/7<\/p>\n

So, the angle subtended at the circumference = 10+100\/7 = 24.28 degrees<\/p>\n

4)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

<\/figure>\n

In triangle AOB, cos (AOC) = $\\frac{\\frac{10}{\\sqrt{2}}}{10} = \\frac{1}{\\sqrt{2}}$ => angle AOC = 45. Similarly angle BOC=45. Now angle AOC+angle =angle AOB = 45+45 =90. Hence, AO is perpendicular to OB.<\/p>\n

Similarly, angle POQ=90<\/p>\n

The angle formed by minor sector of both the arcs will be 90 and the angle formed by the arcs of both the major sectors will be 360-90=270<\/p>\n

For 360 degree the area = area of circle. Hence for 90 degree, the area of the minor sector is (area of the circle)\/4\u00a0 …(1)<\/p>\n

So, the area of major sector of PQ = 270\/360* area of the circle =\u00a03*(area of the circle)\/4\u00a0 …..(2)<\/p>\n

The required ratio = 1:3\u00a0 \u00a0(dividing 1 by 2)<\/p>\n

5)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

\"\"<\/figure>\n

The radius of the circle is $\\sqrt{5^2 + (5\\sqrt3)^2}$ = 10 cm
\nThe angle subtended by the chord at the center is 30+30 = 60 degrees.
\nWe have to find the area of sector AEB (the area enclosed by AEBDA).
\nSo, the area of the sector = 60\/360 * 22\/7 * 10*10 = 2200\/42 = 52.38
\nArea of the triangle is $1\/2*10*5\\sqrt3$ = $25\\sqrt3$ = 43.30
\nSo, the area of the segment is $9.08 cm^2$<\/p>\n

6)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

The radii of both the circles and the line joining the centers of the two circles form a right angled triangle. So, the length of the common chord is twice the length of the altitude dropped from the vertex to the hypotenuse.<\/p>\n

Let the altitude be h and let it divide the hypotenuse in two parts of length x and 25-x<\/p>\n

So, $h^2 + x^2 = 15^2$ and $h^2 + (25-x)^2 = 20^2$<\/p>\n

=> $225 – x^2 = 400 – x^2 + 50x – 625$<\/p>\n

=> 50x = 450 => x = 9 and h = 12<\/p>\n

So, the length of the common chord is 24 cm.<\/p>\n

7)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Let EO = x, So, AE = 3\/2 – x<\/p>\n

AE : EB = 1:2 => x = 1\/2<\/p>\n

So, EO = 1\/2<\/p>\n

Similarly, OL = 1\/2<\/p>\n

Now, EOLH is a parallelogram and EO = OL = 1\/2.<\/p>\n

So, OL = 1\/2<\/p>\n

In triangle DOL, DO = radius = 3\/2 and OL = 1\/2<\/p>\n

So, DL = $\\sqrt2$<\/p>\n

=> DH = $(2\\sqrt2 – 1)\/2$<\/p>\n

8)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

The length of the line joining the center of the hexagon to any of the vertices is same as the side of the hexagon. So, the side of the inscribed hexagon is equal to the radius of the circle = 10 cm. The area of the hexagon is $\\sqrt{3}\/4*10*10*6$ = $150\\sqrt{3} cm^2$<\/p>\n

9)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

The distances of the chords from the center are 12 cm and 16 cm respectively. If the chords lie on the same side of the center, the distance between the chords is 4 cm, if they lie on opposite sides of the center, the distance between them is 28 cm.<\/p>\n

10)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

<\/p>\n

Length of the transverse common tangent = $\\sqrt{50^2-(22+18)^2}=30$ cm<\/p>\n
