Answer: 133.1 units ²
Explanation:
First find the area of the Parallelogram;
= Base * height
= 18 * 6
= 108 units²
Area of a semi circle;
= πr²/ 2
r = diameter/2 = 8/2 = 4
= (π * 4²)/2
= 25.1 units²
Area of both = 108 + 25.1
= 133.1 units ²
Human activity-electricity used day by day . Hyde using electricity heat is produced.
Burning of fossil fuels
Transport-cars
Farming- door example cows produce methane which is a green house gas and leads to global warming.
Examples: humans work in factories , in factories energy is needed, the energy is produced by burning fuels which produce carbon Dioxide. The carbon dioxide increases the temperature.
the cars produce soot and ( I think) it produces a gas ( i forgot the name of the gas butni think.is sulphure dioxide-you have to search up for it) that leads to acid rain

The Vietnam's current level of rice exports challenges that of India.
Answer:
An analysis of 5,000-year-old genetic material from preserved human remains found in Sweden suggests that people moving from southern to northern Europe spread agriculture across that continent long ago.
In addition to agricultural know-how, the intrepid farmers brought their genes: They interbred with hunter-gatherer communities to create modern humans living in Europe today.
"Genetic variation of today's Europeans was strongly affected by immigrant Stone Age farmers, though a number of hunter-gatherer genes remain," study researcher Anders Götherström, of Uppsala University in Sweden, said in a statement.
The results of this study, to be published in the April 27 issue of the journal Science, match up well with previous archeological evidence of farming in Europe.

So we know that 1 km=100,000 centimeters, because 100 cetimeters =1 meter and 1,000 meters=1 km. Multiplying the two gets 100,000. Now there are 7.5 cm, so divide by 100,000 to get distance in km. .000075 is your final answer.
