The base radius of a solid right circular cone is equal to the length of the radius of asolid sphere. If the volume of the sphere is twice of that of the cone, then let us writeby calculating the ratio of the height and base radius of the cone. |
|
Answer» Let, Base radius of a solid right circular cone = Radius of solid sphere = R units HEIGHT of the cone be h units Given : Volume of sphere = 2 × ( Volume of cone ) We know that
⇒ 4/3 × πr³ = 2 × ( 1 / 3 × πr²h ) Cancelling r² ONE both sides since radius of cone and sphere are equal ⇒ 4/3 × πr = 2 / 3 × πh Cancelling π and 2/3 on both sides ⇒ 2r = h ⇒ 2 = h / r ⇒ h / r = 2 ⇒ h : r = 2 : 1 Therefore the RATIO of height and radius of cone is 2 : 1 |

The length of the ABCD square is14 cm, as shown in the figure. M.Each circle draws four congruentcircles centered on A, B, C andD, externally touching two of theremaining three circles. Shaded.Find the area of the part: |
|
Answer» Given: Side of square ABCD = 14 cm Radius of circles with centers A, B, C and D = 14/2 = 7 cm Area of shaded region = Area of square - Area of four sectors subtending RIGHT angle Area of each of the 4 sectors is equal to each other and is a sector of 90° in a circle of 7 cm radius. So, Area of four sectors will be equal to Area of one complete circle Area of 4 sector = πr² 2*22/7 * 7 area of sector = 154cm² Area of square ABCD = (Side)² Area of square ABCD = (14)² Area of square ABCD = 196 cm² Area of shaded PORTION = Area of square ABCD - 4 × Area of each sector = 196 – 154 = 42 cm² Therefore, the area of shaded portion is 42 cm² |

|
Answer» Answer: tanθ = 20/21 = opposite SIDE(o)/adjacent side(a) hypotenuse = h = o² + a² Let , o = 20K and a = 21k h² = (20k)² + (21k)² = 841k² h = 29 k sinθ = o/h = 20k/29k =20/29 cosθ = a/h = 21k/29k = 21/29 sinθ = o/h = 20k/29k =20/29 cosθ = a/h = 21k/29k = 21/29 1 - sinθ + cosθ ÷ 1 + sinθ + cosθ = {1 - 20/29 + 21/29 / 1 } ÷ {1 + 20/29 + 21/29} = {29/29 - 20/29 + 21/29) ÷ {29/29+20/29+21/29} = {29 - 20 + 21/29} ÷ {29+20+21/29} = 30/29 ÷ 70/29 29 gets cancelled on both denominator and NUMERATOR. = 30/70 = 3/7 = RHS Proved. |

The numerically greatest term in the expansion (2x-3y)¹² when x=1 and y= 5/2 is |
|
Answer» Given: (2X-3y)¹² , x=1 and y= 5/2 To find: The numerically GREATEST term in the expansion (2x-3y)¹² when x=1 and y= 5/2 is Solution: From given, we have, (2x-3y)¹², x=1 and y= 5/2 we USE the formula, P = [ (n + 1) |x| ] / [|x| + 1] to find the numerically greatest term. so we have, (2x-3y)¹² = (2x)¹²(1 - 3y/2x)¹² Thus we GET, |x| = (3/2) (y/x) substituting the values of x and y, we get, |x| = (3/2) (5/2) = 15/4 Now consider, P = [ (n + 1)|x| ] / [|x| + 1] P = [ (12 + 1) (15/4)] / [15/4 + 1] P = [ (13) (15/4)] / [19/4] P = 195/19 = 10.26 Thus 10.26 ≈ 11, 11TH term is the numerically greatest term in the expansion (2x-3y)¹² when x=1 and y= 5/2. |

The shape of the lower portion of a solid is hemisphere and the shape of upperportion of it is right circular cone. If the surface areas of two parts are equal, then letus write by calculating, the ratio of the radius and height of the cone. |
|
Answer» A SOLID is FORMED by joining hemisphere and right circular cone So, let Radius of hemisphere = Base radius of cone = R units Let the height of the cone be h units Given :
Surface area of hemisphere = Surface area of right circular cone Here surface area should be considered as Curved surface area as they are combined We know that
⇒ 2πr² = πrl Now, Slant height l = √( r² + h² ) ⇒ 2πr² = πr × √( r² + h² ) Cancelling πr on both sides SINCE radius are same ⇒ 2r = √( r² + h² ) Squaring on both sides ⇒ ( 2r )² = ( √( r² + h² ) )² ⇒ 4r² = r² + h² ⇒ 4r² - r² = h² ⇒ 3r² = h² ⇒ r² / h² = 1 / 3 ⇒ ( r / h )² = 1 / 3 Taking square root on both sides ⇒ √( r / h )² = 1 / √3 ⇒ r / h = 1 / √3 ⇒ r : h = 1 : √3 Therefore the ratio of radius and height is 1 : √3. |

Write two integer whuch are smaller than -6 but their difference is greater than -6 |
|
Answer» Step-by-step explanation: Rules for ADDING Integers When adding integers of the same sign, we add their absolute values, and GIVE the result the same sign. The SUM of two+positive integers is a positive+integer. The sum of two+negative integers is a negative+integer. To find the sum of a positive and a negative integer, find the absolute value of each integer and then subtract these values. The result TAKES the sign of the integer with the larger absolute value. We know that negative numbers are smaller as their absolute value is greater. So, in your case, we can say that the sum of ANY two NEGATIVEintegers is smaller than both the integers. |

Difference between infinity and not defined |
|
Answer» Infinity is nothing but greater than EVERY real number. It's a concept, not a number, though there are "numbers" ASSOCIATED to collections of INFINITE objects, but that's a HUGE area of maths, not suitable for an answer, maybe a book. "Not defined" MEANS, well that what you have cannot be defined. |

Find the root of the following quadratisequation (if they exist) by theMethod of ouaduatic Formula.2x^2 + 5root3x + 6 = 0 |
|
Answer» Step-by-step explanation: GIVEN - polynomial is 2x² + 5√3x + 6 = 0 To Find - Roots of the polynomial by Quadratic formula. Now, 2x² + 5√3x + 6 = 0 here, a = 2 B = 5√3 c = 6 Quadratic formula = - b ± √b² - 4ac/2a = -(5√3) ± √(5√3)² - 4 × 2 × 6/2(2) = -5√3 ± √75 - 48/4 = -5√3 ± √27/4 = -5√3 ± 3√3/4 Hence, The roots of the polynomial 2x² + 5√3x + 6 = 0 is x = -5√3 + 3√3/4 = -2√3/4 = -√3/2 and x = -5√3 - 3√3/4 = -8√3/4 = -2√3 Formula Used -x = -b ± √b² - 4ac/2a |
