A cone, placed on a table, is cut from the middle by a horizontal plane. The lower portion is placed in inverted position & upper portion is placed symmetrically on it. Calculate the total visible area (Take R = 14 cm, Pi = 22/7 and h = 48 cm)
A circular cone with height 24 and radius 6 is placed on its circular face on a table. It is then cut by a horizontal plane, which is parallel to the circular base and passes through the midpoint of the height. The volume of the lower part of the cone can be written as A*PI.
What is the value of A?
A spherical shell of mass m is resting on the rough horizontal plane with a coefficient of friction 0.3 a horizontal force act at a distance of 5r/3 from the baseline where r is the radius of the sphere. Find work done by friction body has moved by a distance of gm/r from the initial position?
A pattern of triangles is shown below. Fill in the table for figure 5. Calculate the total number of triangles in figure 250. Calculate the percentage of grey triangles in figure 250.
What is an open plane curve formed by the intersection of a cone with a plane parallel to its side, resembling the path of a projectile under the action of gravity?
