A gulabjamun when completely ready for eating contains sugar syrup up to about 30% of its volume. Find approximately how much syrup would be found in 45 gulabjamuns shaped like a cylinder with two hemispherical ends, if the complete length of each of the gulabjamun is 5 cm and its diameter is 2.8 cm.

A medicine -capsule is the shape of a cylinder of diameter 0.5 cm with two hemisphere stuck to each of its ends. The length of entire capsule is 2cm. The capacity of the capsule is

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.)

The length of a cylinder is measured with a meter rod having least count 0.1 cm . Its diameter is measured with Vernier calipers having least count 0.01 cm . Given that length is 5.0 cm and radius is 2 cm . Find the percentage error in the calculated value of the volume.

A container in the shape of a frustum of a cone having diameters of its two circular faces as 35 cm and 30 cm and vertical height 14 cm, is completely filled with oil. If each cm^(3) of oil has mass 1.2 g then find the cost of oil in the container if it costs ₹40 per kg.

Shubham pal an engineering student was asket to make a model shaped like cylinder wih 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 32 cm , find the volufme of air contained i the model that shubham pal made. (Assume the outer and inner dimensions of the model to be nearly the same).

Mathematics teacher of a school took her 10th standard students to show Red fort. It was a part of their Educational trip. The teacher had interest in history as well. She narrated the facts of Red fort to students. Then the teacher said in this monument one can find combination of solid figures. There are 2 pillars which are cylindrical in shape. Also 2 domes at the corners which are hemispherical.7 smaller domes at the centre. Flag hoisting ceremony on Independence Day takes place near these domes. What is the ratio of sum of volumes of two hemispheres of radius 1cm each to the volume of a sphere of radius 2 cm?

A milk container is made of metal sheet in the shape of frustum of a cone whose volume is 10459(3)/(7)cm^(2). The radii of its lower and upper circular ends are 8cm and 20cm respectively. Find the cost of metal sheet used in making the container at the rate of Rs.1.40per square centimeter.

Hanumappa and his wife Gangavva are busy making Jaggery out of sugar-cane. They have processed the sugarcane juice to make the molasses which is poured into moulds of the shape shown in Fig 16.72. It will be cooled to solidify in this shape to be sent to the market. Each mould is in the sh ape of a frustum of a cone having the diameters of its two circular ends as 30 cm and 35 cm and the height of the mould is 14 cm. If each c m^3 of molasses weighs about 1.2 gm, find the weight of molasses that can be poured into each mould (Take pi=22//7 )
