Objects like football, volleyball, throw ball, etc., are said to have the shape of a sphere.

In geometry, the solid generated by revolving a circular lamina about any of its diameters, is called a sphere.

The centre and radius of this circle are called respectively the centre and the radius of the sphere.

The solid generated by the rotation of a right angled triangle about one of the sides containing the right angle is called a right circular cone.

We see around us many objects such as an ice-cream cone, a conical vessel, a clown’s cap, etc., The objects are said to have the shape of a right circular cone.

Solids like iron pipes, rubber tubes, etc., are in the shape of hollow cylinders.

(a) \(\sqrt2\) m

Let the inner radius of pipe be r m. 

Then, 440 = \(\frac{22}{7}\times{r}^2\times7\times10\)

⇒ r² = \(\frac{440}{22\times10} = 2\) ⇒ r = \(\sqrt2\) m.

Cylinder solids like circular pillars, circular pipes, circular pencils, measuring jars, road rollers and gas cylinders, etc., are said to be in cylindrical shapes.

Correct option is (C) 48 cm²

\(\therefore\) Curved surface area of formed cylinder = Area of rectangular sheet

= 12 \(\times\) 4 \(=48\,cm^2\)

Correct option is C) 48 cm²

A cuboid whose length, breadth and height are all equal is called a cube.

It is given in the question that, 

Diameter of the wire = 1cm 

Hence, 

Radius of the wire = 0.5 cm 

Length or the height of the wire = 11 cm 

Hence, 

The volume of the wire = \(\pi r^2h\)

= \(\frac{22}{7}\times0.5\times0.5\times11\)

= 8.643 cm³

Now, 

We know that, 

The volumes of both the cylinders would be the same. 

And, 

Diameter of the new wire = 1mm = 0.1 cm 

Radius = 0.05 cm 

Therefore the new length of the wire would be = \(\frac{volume}{\pi r^3}\)

= \(\frac{8.643\times7}{22\times0.05\times0.05}\)

= 1100.02 cm 

= 11 m

A solid bounded by six rectangular faces is called a cuboid.

A match box, a chalk box, a brick, a tile, a book, etc., are all examples of a cuboid.

A cuboid has 6 rectangular faces, 12 edges and 8 vertices.

The Area occupied by a solid body is called its Surface Area.

The units of Surface Area are square centimeters (written as cm²) or square meters ( written as m²)

It is given in the question that 

Length of the edge, a = 2.2 cm 

Hence, 

Volume of the cube = a³ 

= (2.2)³ 

= 10.648 cm³ 

Now, 

Volume of the wire \(=\pi r^2h\)

Radius of the wire = 1mm = 0.1cm 

We know that, 

Volume of the cube = volume of the wire 

Hence, 

Length of the wire = \(\frac{volume}{\pi r^2}\)

= \(\frac{10.648\times7}{22\times0.1\times0.1}\)

= 338.8 cm

D) solids – surface – lines – points

The space occupied by a solid body is called its volume.

The units of volume are cubic centimeters (written as cm³ ) or cubic metres (Written as m³)

The bodies occupying space are called solids.

The solid bodies occur in various shapes such as: a cuboid, a cube, a cylinder, a cone, a sphere, etc.

Once the rturation is completed, the partnership dissolves automatically. However, if the partners wish to extend the duration they can.

3. Partnership for a specific work:

• Partnership firm with unlimited liability: The partnership firm in which the liability of each member is unlimited is called a partnership firm with unlimited liability.

(C) Partnership according to business:
1. Banking firm:

• A partnership firm that accepts deposits from public and as per specific conditions lend money to the customers is called a banking firm.
• A banking firm has minimum 2 partners and maximum 10 partners.

2. General (Non-banking) firm:

• A partnership firm created for any legal activity other than banking is called a general partnership firm.
• This firm can.have minimum 2 partners and maximum 20.

(D) Partnership according to registration:

The committees took care of irrigation, roads, temples, gardens, collection of revenue and conduct of religious festivals.

1. The chola rulers established a well organized system of administration in which the empire was divided into mandalans, naadu, Kurrams and gramam.

2. A very efficient local administration was another important feature of the Chola rule.

4. The Chola rulers built the famous temples in Thanjavur, Gangaikonda Cholapuram and Darasuram. Chola Kings were great patrons of learning. Trade flourished during their period.

The revenue of the Chola state came mainly from the land. The land tax was known as Kanikadan. The Chola rulers carried out an elaborate survey of land in order to fix the government’s share of »the land revenue. One-third of produce was collected as land tax. It was collected mostly in kind.
