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

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

<\/figure>\n

Total curved surface area = $2\\pi rh + 2\\pi r^2$ = $2(22\/7)(7)(7) + 2(22\/7)(7)^2 = 616sq.cm$<\/p>\n

So the answer is option A.<\/p>\n

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

Area of trapezium = $\\frac{1}{2}$(sum of parallel sides)$h$ = $\\frac{1}{2}(8+4)(6) = 36$sq.cm<\/p>\n

So the answer is option D.<\/p>\n

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

Vol.of cylinder : Vol.of cone<\/p>\n

= $\\pi r^2 h : \\frac{1}{3}\\pi r^2 h$<\/p>\n

= $\\pi (6)^2(4) : \\frac{1}{3}\\pi (4)^2(6)$<\/p>\n

= $18 : 4$<\/p>\n

= $9 : 2$<\/p>\n

So the answer is option B.<\/p>\n

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

Length of rectangle = 9 cm<\/p>\n

Breadth = side of square = \u221a36 = 6 cm<\/p>\n

Perimeter = 2(l+b) = 2(9+6) = 30cm<\/p>\n

So the answer is option B.<\/p>\n

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

Area of trapezium = $\\frac{1}{2}(a+b)h = \\frac{1}{2}(7+5)(4) = 24sq.cm$<\/p>\n

So the answer is option B.<\/p>\n

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

Volume of cuboid = lbh = 12*8*10 = 960 cm\u00b3<\/p>\n

Volume of cube = 2\u00b3 = 8 cm\u00b3<\/p>\n

No.of cubes = $\\frac{960}{8} = 120$<\/p>\n

So the answer is option B.<\/p>\n

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

If internal angle of a regular polygon is 120\u00b0, it is regular hexagon,<\/p>\n

No.of diagonals of a polygon of n sides = $n(n-3)\/2 = 6(6-3)\/2 = 6(3)\/2 = 9$<\/p>\n

So the answer is option B.<\/p>\n

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

Area of parallelogram = base*height = 8*5 = 40 sq.cm<\/p>\n

So the answer is option B.<\/p>\n

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

Area of sector = $\\frac{x}{360}\\times \\pi (r)^2$ = $\\frac{51}{360}\\times \\frac{22}{7}(7)^2 \\sim 22sq.cm$<\/p>\n

So the answer is option C.<\/p>\n

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

Let h be the height, then<\/p>\n

2(lb+bh+hl) = 94<\/p>\n

2(20+4h+5h) = 94<\/p>\n

(20+9h) = 47<\/p>\n

9h = 27<\/p>\n

h = 3<\/p>\n

So the answer is option C.<\/p>\n\n
