The distance around a shape or figure I called Perimeter. A perimeter is a path that surrounds a two-dimensional shape.

We know that polar substances are soluble in polar solvents and non polar substances are soluble in non-polar solvents only. Here the hydrocarbons are non-polar molecular substances and water is a polar solvent. So water can't dissolve hydrocabons.

Hence, as hydrocarbons are non-polar substances, they are insoluble in water as it is a highly polar solvent. 

 The formula to find the volume is given by just multiplying Length, Breadth and Height of that object. 

 Thus, V = L x B X H  

Volume Formulae :   

1. Volume of Cube of side 's' = s x s x s = s3  cubic units.   

2. Volume of Cylinder = πR2h cubic units.  

[Where R is Radius and h is height]

Given Loss = Rs. 40.4
We know loss = cost price - selling price
40.4 = CP - 35(15)
=> CP = 40.4 + 525
=> CP = Rs. 565.4
Now the New selling price of waffer is Rs. 18
=> SP = 35(18) = 630
Now Gain = SP - CP = 630 -565.4 = Rs. 64.6.

A half reaction is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction.

"Cuba" is the name of the country which was commonly known as the "Sugar Bowl of the World".

It is called by this name because formerly it was the largest producer of Sugar, but now Brazil is currently the largest producer of Sugar.

It is an island country in the Caribbean and is officially called as the Republic of Cuba.

Producer are Autotrophs as they prepare their own food and does'nt depend on others as Customers or Heterotrophs which depend on producers or Autotrophs.
