What is the area of the remaining part in sq units? None of these http: Find the perimeter of the square ABCD. In the following figure, AB touches the circle at P. On a semicircle with diameter AD, chord BC is parallel to the diameter. Let 1 S be a square of side a. Another square 2 S is formed by joining the mid-points of the sides of 1 S.

The same process is applied to 2 S 2 3 , , S S S , respectively, then the ratio 1 2 3 1 2 Consider a circle with unit radius. There are seven adjacent sectors, 1 2 3 7 , , What is the angle, in radius, subtended by the arc of 1 S at the centre of the circle? Then, the ratio of the area of the circle to that of the square is http: C C C be circles with diameters 1 1 2 2 3 , , Suppose the circles 1 2 3 , , , C C C are all shaded. The ratio of the area of the unshaded portion of C to that of the original circle C is a.

A right triangle contains a 60 o angle. If the measure of the hypotenuse is 4, find the distance from the point of intersection of the 2 legs of the triangle to the point of intersection of the angle bisectors.

Find the radius of the circle that is inscribed between two sides of the square and the original circle. AB is a diameter of circle O, as shown in Fig. Two circles are drawn with AO and OB as diameters. In the region between the circumferences, a circle D is inscribed, tangent to the three previous circles.

If the measure of the radius of circle D is 8, find AB. A circle is inscribed in a quadrant of a circle of radius 1 unit. What is the area of the shaded region? Because the two figures are similar, all cones angles would be equal. Hence perimeter of rem. If we rotate the portion ABGO about the x- http: The same would be true for the cone. In a triangle, the side opposite to 30 o is half the hypotenuse. Therefore 7 triangles.

For an acute- angled triangle, square of any side is less than the sum of the squares of the other two sides. The values of n satifying the above conditions are 22, 23, 24 and Therefore 4 values. The triangles possible are 1, 3, 3 , 2, 2, 3. Others triangles are not possible as sum of two sides will not be greater than the third side.

Therefore the area decreases by 1. In the given triangle, as the height for triangle ABD and ADC is the same, the ratio of the areas of the two triangles are in the ratio of their bases. Therefore values of x are 9, 10, 11, 12…. Since DE is perpendicular bisector of BC. Let PQ be the height of the intersection of wires.

Answer Find the radius of each circle and determine the order. Equal chords subtend equal angles in a circle. By similarity, the radius 1 r and 2 r will be 1 3 r and 2 3 r. The distance traveled by Ant would be minimum if it travels as in the figure. Six tiles can be accommodated as given in the figure. If we look at the horizontal orientation only the last step of the 4 th floor is 2 2ft. Similarly 8 th floor is 2 2 ft. So the top of th floor is So the distance between the final and initial point is 2 2 50 2 Hence Answer 2.

The ratio of the base areas for the two cylinders is 2 2 1: If we form a circle, taking AC as diameter. The path of the ant is given in the figure below: The radius of such sphere would be same as the radius of in circle of the cross section of come.

Therefore, the remaining volume would be 5 6 th the volume of the sphere, i. In this process the volume of n cones. Would be equal to the volume of the cylinder. In this process the volume of the new cube would be equal to the sum of volume of the three smaller cube. From the figure it is clear that only half of the volume of cylinder is filled with soft drink and the remaining half is empty.

If we consider only one villi. Since all the solids are made up of same material. So that their weight are directly proportional to their volume.

When we observe the length of the rod from the side, front and bottom, we get the length of side face diagonal, front face diagonal and bottom face diagonal. If we take the cross section of the pyramid it would look like the same as shown in the figure: In the above figure CB, represents the water surface. If we till the bowl the water will start spilling as the point B coincide with point e.

Let the lines of folds be PQ and QR. The folded piece would be symmetrical about the line of fold. ABD is an equilateral triangle. Since E and F are the midpoints of the side P would also be a midpoint. Similarly, we can slows that S would also be a midpoint. The angle bisectors of two interior supplementary angles intersect at 90 o. Therefore the quadrilateral formed would be a rectangle. Let the quadrilateral be PQRS as shown in the figure. It can be seen that EBCO is a parallelogram.

Option c Use pythegoreon triplets of 17, 15, 8 and 5, 3, 4. Join O to Q http: At PQR be the given triangle. Their in radius would be in the ratio of their sides. Drop a perpendicular from P to vertical line passing through Q. Join E and F. The height and radius of the cone at height 5cm are of height and radius of the original one and volume is one-eighth.
