Iron is a shiny, bright white metal that is soft, malleable, ductile and strong. Its surface is usually discolored by corrosion, since it combines readily with the oxygen of the air in the presence of moisture. In absolutely dry air, it does not rust

1 answers

Yogita Ingle 5 years, 9 months ago

1 km = 1000 m; 1 hr = 3600 sec.

{tex}1 km/hr = 1000/3600 m/sec = 5/18 m/sec{/tex}

To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.

72 km/hr = (72) 5/18 = 4 (5) =20 m/s

ANSWER

A circular flower bed is surrounded by a path of 4m wide. The diameter of the flower bed is 66 m. What is the area of the path?

Posted by Balraj Gaikwad 5 years, 9 months ago

CBSE > Class 07 > Mathematics

1 answers

Yogita Ingle 5 years, 9 months ago

Radius of flower bed = 33 m (Diameter/2=radius)....

Radius of flower bed and path together = 33 + 4 = 37m....

So, Area of flower bed (path together )= 3.14 × 37 × 37 = 4298.66 m²

Area of flower bed = 3.14 × 33 × 33 = 3419.46 m²

Area of path = Area of flower bed and path together − Area of flower bed = 4298.66 − 3419.46 = 879.20 m²

What are the advantages of road transport as against rail transport

Posted by Shubham Kerketta 5 years, 9 months ago

CBSE > Class 07 > Social Science

1 answers

Yogita Ingle 5 years, 9 months ago

Road transport is more important than railway transport in many ways.

Road transport delivers people and goods at door.
Road transport generates more employment than railway transport.
It is easy to have access over hilly areas whereas it is not possible with railway transport.
For laying of roads it costs less and consumes less time but to lay tracks for railway transport it is opposite.
During emergency(war, accident etc) Road transport is widely useful/used.
When an accident takes place the chances of casualties are more in railway transport when comparing with Road transport.

Yogita Ingle 5 years, 9 months ago

Sorry bi-mistake take 100 in place of 150. So, please solve it as per changes.

0Thank You

Yogita Ingle 5 years, 9 months ago

Perimeter of rectangle = 150m

ratio of length is to breadth = 2:3 = 2x : 3x

Perimeter = 2(l+b)

P = 2(3x+2x)

10x = 100

x = 100/10 = 10

l = 2x = 2 × 10 = 20 m

b = 3x = 3× 10 = 30 m
