A compnay packages its milk powder in cylindrical container whose base has a diameter of 14 cm and height 20 cm.Company places a label around the surface of the container (as shown in the figure).If the label is placed 2 cm from top and bottom,what is the area of the label?

A cylindrical vessel open at the top has a dimeter 20 cm and height 14 cm. Find the cost of tin-plating it on the inside at the rate of 70 paise per 100 cm^2 .

A hemisphere, the diameter of whose base is equal to the side of a cube, is placed upon the upper face of the cube. If the side of the cube is 14 cm, find the total surface area of the solid combination.

The rain water from a roof 22 m xx 20 m drains into a cylindrical vessel having diameter of base 2 m and height 3.5 m. If the vessel is just full, find the rainfall in cm

A wooden article was made by scooping out a hemisphere from each end of a solid cylinder, as shown in the figure. If the height of the cylinder is 10 cm and its base is of radius 3.5 cm, find the total surface area of the article.

From a solid cylinder whose height is 2.4 cm and diameter 1.4cm,aconical cavity of the same height and same diameter is hollowed out. Find the total surface area of the remaining solid to the nearest cm^2 .

A small coil is positionaed so that its axis lies along the axis of a large bar agnet, as shown in the figure. The coil has a cross-sectional area of 0.40 cm^2 and contains 150 turns of wire. The average magnetic flux density B through the coil aries with the distance x between the face of the magnet and the plane of the coil as shown in the figure. The coil is 5.0 cm from the face of the magnet to determine the magnetic flux density in the coil.

A bus stop is barricaded from the remaining part of the road, by using 50 hollow cones made of recycled cardboard. Each cone has a base diameter of 40 cm and height 1 m. If the outer side of each of the cones is to be painted and the cost of painting is Rs 12 per m^2 , what will be the cost of painting all these cones (use pi = 3.14 , and take sqrt(1.04)=1.02 ) ?

A powder tin has a square base with side 12 cm and height 17.5 cm. another is cylindrical with diameter of its base 12 cm and height 17.5 cm. which has more more capacity and by how much?

Rachel, an engineering student, was asked to make a model shaped like a cyclinder. with two cones attached at its two ends by using a thin aluminium sheet. The diameter of the model is 3 cm and its length is 12 cm. If each cone has a height of 2 cm, find the volume of air contained in the model the Rachel made. (Assume the outer and inner dimensions of the model to be nearly the same.)
