A bucket is in the form of a frustum of a cone ad holds 28.490 liters of water. The radii of the top and bottom are 28cm and 21cm respectively. Find the height of the bucket.

a. 20 cm

b. 15 cm

c. 10 cm

d. None of the above

Solution

Lead spheres of diameter 6cm are dropped into a cylindrical beaker containing some water and are fully submerged. If the diameter of the beaker is 18cm and water rises by 40cm. find the no. of lead sphere dropped in the water.

a. 90

b. 150

c. 100

d. 80

Solution

A petrol tank is a cylinder of base diameter 21cm and length 18cm fitted with conical ends each of axis length 9cm. Determine the capacity of the tank

a. 8316cm

b. 9456 cm

c. 10160 cm

d. None of the above

Solution

A cone, a hemisphere and a cylinder stand on equal bases and have the same height. Show that their volumes are in the ratio 1: 2: 3.

Solution

The radii of the basses of two right circular solid cones of same height are r

$h=\frac {4R^3}{r_1^{2} + r_2^{2}}$

Solution

Prove that the surface area of a sphere is equal to the curved surface area of the circumscribed cylinder.

Solution

A bucket of height 8cm and made up of copper sheet is in the form of frustum of a right circular cone with radii of its lower and upper ends as 3cm and 9m respectively.

Calculate –

- the height of cone of which the bucket is a part.
- the volume of water which can be filled in the bucket.
- the area of copper shut required to make the bucket.

500 persons are taking a dip into a cuboidal pond which is 80 m long and 50 m broad. What is the rise of water level in the pond, if the average displacement of the water by a person is 0.04m

Solution

The slant height of the frustum of a cone is 4cm, and the perimeter of its circular bases is 18cm and 6cm respectively. Find the curved surface area of the frustum ?

Solution

True and False

a. Total surface area of a lattu (top) as shown below in figure is the sum of total surface area of hemisphere and the total surface area of cone.

b. A funnel shown in below figure is the combination of frustum of a cone and a cylinder

c. Actual capacity of a vessel as shown in below figure is equal to the difference of volume of the cylinder and volume of the hemisphere
