Now the longest piece is clearly 3 times the middle sized piece and hence option 3 satisfies all the conditions and thus option 3 is answer. Suggested Article : Q3: 3 identical cones with base radius r are placed on their bases so that each is touching the other two.
The radius of the circle drawn through their vertices is 1. Depends on the height of the cone. Just try to visualize the three cones from their heads. The central point between the three is definitely at a distance, which is more than the radius; hence third option is the answer.
Otherwise; just check if you have taken three equal circles who are touching the other two, the circle which will cover those three circles will be definitely the radius of the smaller circle plus something. Now it should be sufficient to conclude that it is more than r.
Q4: In the following figure the smallest cone has base radius 2 cm and height 1 cm. The heights of successive cones from the top form a G.

What shall be the ratio of the volumes of the smallest cone, to the two following frustrums? None of these Solution: We get the heights of the successive cones as 1, 2 and 4. But the question is asking about the smallest cone to the frustum. Published in: Full Name Comment goes here.

The sum of interior angles of a polygon having n sides is 2n — 4 right angles. If any value of sides decreased, then put "-" value in the formula. For circle diameter or radius changed instead of sides.
If the area of the square is a unit, then the area of the circle formed by the same perimeter.
Area of a square inscribed in a circle of radius "r" is equal to 2r. The area of the largest triangle inscribed in a semi-circle of radius "r" is equal to "r ". If sides of 2D figure either increased or decreased, then P also either increased or decreased respectively.
If the ratio of areas of 2 squares be a: Cylinder A cylinder is a solid or hollow body and it is formed by keeping of circles of equal radii one upon another. It can also formed by rolling a rectangular sheet. Frustum of Cone If pointed top of cone cut as parallel to base, the resultant lower part of cone is called as frustum.
All points on its space having constant distance from fixed center point. Top and bottom faces are rectangles and are called lateral faces.Abhishek Anand , Student at G.

If any value of sides decreased, then put "-" value in the formula. This is what fraction of the original surface area i. WordPress Shortcode. Depends on the height of the cone.
