Question

The diameter of the ends of a bucket of height 24 cm are 42 cm and 14 cm
respectively .Find the capacity of the bucket

  1. 16016 cm3
  2. 1616 cm3
  3. 6016 cm3
  4. 61160 cm3

Hint:

Volume of frustum of cone = fraction numerator pi h over denominator 3 end fraction open square brackets fraction numerator open parentheses R cubed minus r cubed close parentheses over denominator R minus r end fraction close square brackets

The correct answer is: 16016 cm3


    We have given the dimensions of a bucket which is of frustrum shape
    Top diameter = 42 cm
    Top radius, R = 21 cm
    Bottom diameter = 14
    Bottom radius, r = 7 cm
    Height of frustrum , h = 24 cm
    Therefore capacity of bucket = volume of bucket

    equals fraction numerator pi h over denominator 3 end fraction open square brackets fraction numerator open parentheses R cubed minus r cubed close parentheses over denominator R minus r end fraction close square brackets

    equals fraction numerator left parenthesis 22 divided by 7 right parenthesis left parenthesis 24 right parenthesis over denominator 3 end fraction open square brackets fraction numerator open parentheses 21 cubed minus 7 cubed close parentheses over denominator 21 minus 7 end fraction close square brackets

    left parenthesis 22 right parenthesis left parenthesis 8 right parenthesis open square brackets fraction numerator open parentheses 21 cubed minus 7 cubed close parentheses over denominator 7 cross times 14 end fraction close square brackets

    left parenthesis 176 right parenthesis open square brackets fraction numerator left parenthesis 9261 minus 343 right parenthesis over denominator 98 end fraction close square brackets

    left parenthesis 176 right parenthesis open square brackets fraction numerator left parenthesis 8918 right parenthesis over denominator 98 end fraction close square brackets

    = 176 × 91

                                                                          equals 16016 cm cubed
    Therefore, the correct option is a)16016 cm3

    Find the height of a cuboid whose base area is 180cm2 and volume is 900cm2

    Volume of cuboid = Base area × Height  [Cubic units]
    The base of the cuboid is rectangle in shape. So, the base area of a cuboid is equal to the product of its length and breadth. Hence,
    Volume of a cuboid = length × breadth × height    [cubic units]
    or
    Volume of a cuboid = l × b × h    [cubic units]
    Where,
    • l = length
    • b = breadth
    • h = height
    We have given that,
    Base area of cuboid
     = length × breadth = 180 cm²
    Volume of cuboid = length × breadth × height = 900 cm³
    • We will get,
    Volume of a cuboid = Base area of cuboid × height of the cuboid
    900 cm³ = 180 cm² × height
    • On dividing both sides by 180 we get,
    height = 900 over 180 = 5 cm
    Thus, the height of the cuboid is 5 cm.
    The correct option is c) 5 cm .

    calculate the surface area of a cube with a side of 4 mm

    • Step 1:We have given the length of the side of the cube.

    Side = 4 mm

    • Step 2: Find the square of the length of the side of the cube.
    (Side)2= (4)2= 16 mm2
    • Step 3: For total surface area, find out the product of the square of side length by 6.
    Surface area = 6(side)2

    = 6(16)

    = 96 mm2

    • Step 4: Therefore, the surface area of the given cube is 96 mm2.
    • Therefore, the correct answer is option B) 96 mm2.

    Ratio of volume of a cone to the volume of a cylinder for same base radius and
    same height is __________

    Solution :- Here is the activity for finding the volume of cone
    Let us take a cylinder  of height "h", base radius "r", and take 3 cones of height "h". Fill the cones with water and empty out one cone at a time


    Each cone fills the cylinder to one-third quantity. Hence, such three cones will fill the cylinder. Thus, the volume of a cone is one-third of the volume of the cylinder.
    Volume of cone = (1/3) × Volume of cylinder
    = (1 third) × πr2h
    = (1 third)πr2h
    So the ratio of volume of cone to the volume of cylinder is 1:3
    Therefore , the correct option is b) 1:3
