10M11+10M13 - Constructions + Surface Areas & Volumes Objective Test - Answers & Solutions - Set A Q9. (C) i.e., Q10. (C) T he amount of material inside the cylinder will remain the same. Hence, the volume of cylinder must also remain the same. Hence, I is false. If the radius of the new cylinder is and its volume is the same, it means: Hence, III is false. Now with this new radius and height, surface area of cylinder becomes Surface area of original cylinder. Hence, II is Q11. true. Q12. (B) =Area of triangular face height Volume of combined solid= + (D ) Suppose the level of the water in the tank will rise by in , so in hours. Since, the water is flowing at the rate of hours, length of water equals We have, D iameter of cylindrical pipe Radius of cylindrical pipe, Volume of the water flowing through the cylindrical pipe in hours Also, volume of the water that falls into the tank in hours Volume of the water flowing, through the cylindrical pipe in hours = Volume of water that falls in the tank in hours Hence, the level of water in the tank will rise by in hours. (A) Q13. Q14. If and then Since point divides in the ratio , that is into parts, . Hence, . G eneral Case: and For any two positive integers always. T herefore, always. (B) G iven, radius of cylinder and hemisphere Height of cylinder Total surface area of container = Area of base + CSA of cylinder + CSA of hemisphere Q15. Hence, the total surface area of the container is (A) using compass and scale as It is possible to divide a line segment in the ratio As point lies outside the circle [ ], it is possible to draw pair of tangents from this point to the circle.
