A medicine capsule is in the shape of a cylinder with two hermispheres stuck to each of its end [see te given figure]. The length of the entire capsule is 14 mm and the dimaeter of the capsule is 5 mm. find the surface area.

A medicine capsule is in the shape of a cylinder with two hemispheres stuck to each of its ends. The length of the capsule is 14 mm and the thickness is 5 mm. Find its surface area.

Mayank made new a bird-bath for his garden in the shape of a cylinder with a hemispherical depression at one end [ see the given figure]. The height of the cylinder is 1.45 m and its radius is 30 cm. Find the total surface area of the bird- bath. (Take pi=(22)/(7))

A wooden article was made by scooping out a hemisphere from each end of a solid cylinder. As shown in the given 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.

A wooden toy rocke is in the shape of a cone mounted on a cylinder, as shown in the given figure. The height of the entire rocket is 26 cm, while the height of the conical part is 6 cm, the base of the concial protion has a diameter of 5 cm, while the base diameter ofthe cylinderical protion is 3 cm. if the concial portion is tobe painted organe and the cylinderical portion yellow. Find the area of the rocke painted with each of these colours. (Take pi=3.14)

Shanta runs an industry in a shed which isin the shape of a cuboid surmounted by a half cylinder (see the given figure). If the base of the shed is of dimension 7mxx15 m , and the hegiht of the coboidal portion is 8m find the volume of air that the shed can hold. Further suppose te machinery in the shed occupies a total space of 300 m^(3) , and there are 20 workers, each of whom occupy about 0.08 m^(3) space on an average . Then how much air is in the shed ? (Take pi=(22)/(7))

Rasheed got a playing top (lattau) as his birthday present which surprisingly had no colour on it. He wanted to colour it with his cryons. The top is shaped like a cone surmounted by a hemisphere (see the given figure). The entire top is 5 cm in height and the diameter of the top is 3.5 cm. Find the area he has to colour. ( Take pi =(22)/(7) )

A fez, the cap used by the Turks, is shaped like the frustum of a cone (see the given figure). If its radius on the open side is 10 cm, radius at the upper side is 4 cm and its slant height is 15 cm, find the area of material used for making it.

Rachel, an engineering student, was asked to make a model shaped like a cylinder 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 that Rachel made. (Assume the outer and inner dimensions of the model to be nearly the same.)
