Write a diary entry about how you decide to cheer him up to overcome his grief. Write in words. 2) Describe a recent visit to a national park or wildlife century in words. 3) Create your own original short story ( of a minimum of 250 words) about a fictional experience of the accidental tourist ( the character from the chapter: "The accidental tourist"-moments) 4) Revise Chapters 1-5(of both Prose and Poetry section) from Beehive. MATHEMATICS #NOTE- Solve the worksheet in register. 1. Find the number of small cubes with edge 20 cm that can be accommodated in a cubical box of 2 meter edge. 2. Shanta had to make a model of a cylindrical kaleidoscope for her science project. She wanted to use chart paper to make the curved surface of the kaleidoscope, what would be the area of chart paper required by her, if she wanted to make a kaleidoscope of length 25 cm with a 3.5 cm radius? take π =22/7 3. The height of a cone is 16 cm and its base radius is 12 cm. Find: (i) the curved surface area, (ii) total surface area of the cone. [Use π = 3.14] 4. If the slant height and the base radius of a cone are 10 cm and 8 cm respectively, then find (i) curved surface area and (ii) total surface area. [Take π = 3.14] 5. The hollow sphere in which the circus motor cyclist performs his stunts, has a diameter of 7 m, Find the area available to the motor cyclist for riding. 6. A hemispherical dome of a building needs to be painted. if the circumference of the base of the dome is 17.6 m, find the cost of painting it, given the cost of painting is Rs. 5 per 100 cm2. 7. A wall of length 10 m was to be built across an open ground. The height of the wall is 4 m and thickness of the wall is 24 cm. If this wall is to be built up with bricks whose dimensions are 24 cm 12 cm 8 cm, how many bricks would be required? 8. The pillars of a temple are cylindrical shaped. if each pillar has a circular base of radius 20 cm and height 10 m, how much concrete mixture would be required to build 14 such pillars? 9. The sides of a right triangle are 7 cm, 24 cm and 25 cm. If it is revolved about its side 7 cm to form a solid cone find the volume of the solid so formed. 10. Two cones have their base radii in ratio of 3 : 1 and the ratio of their heights as 1 : 3. Find the ratio of their volumes. 11. If the heights of two cylinders are in the ratio of 4 : 3 and their radii are in the ratio of 3 : 4 then what is the ratio of their volumes? 12 If the radius of the base of a solid cone is 'r' and its slant height is 1 then what is its lateral surface area? 13. What is the total surface area of a cone, whose radius and slant height = 31? 14. If a right circular cone has radius 4 cm and slant height 5 cm then what is its volume?

2 15. The radius of a hemisphere is r. What is its volume? 16. If the radius of a sphere is 2 r, then what is its volume? 17. If the radius of a sphere is doubled then what is the ratio of their volumes? 18. AD is a diameter of a circle and AB is a chord. If AB = 30 cm and its perpendicular distance from the centre of the circle is 8 cm, then what is the length of the diameter AD. 19. A chord AB of a circle with centre O is 10 cm. If the chord is 12 cm away from centre, then what is the radius of the circle? 20. If the diameter AD of a circle is 34 cm and the length of a chord AB is 30 cm. What is the distance of AB from the centre? 21. What is the length of a chard which is at a distance of 4 cm from the centre of a circle of radius 5 cm? 22. If the radius of a circle is 13 cm and the length of its chord is 10 cm then what is the distance of chord from the centre? 23. Two circles having radii 5 cm and 3 cm intersect each other at two distinct points. If the distance between their centres is 4 cm, then what is the length of the common chord? 24. A shopkeeper has one spherical laddoo of radius 5 cm. With the same amount of material, how many laddoos of radius 2.5 cm can be made? 25. In figure, PQ is a diameter of a circle with centre O. If PQR = 65 0, SPR = 40 0, PQM = 50 0, find QPR, PRS and QPM. 26. ABCD is a cyclic quadrilateral whose diagonals intersect at a point E. If DBC = 70 0, BAC is 30 0, find BCD. Further, if AB = BC, find ECD. PHYSICS Holiday Homework (PHYSICS) Winter Break Q1. Which force governs the motion of the moon around the Earth? Explain it. Q2.
