Answer:
1.16 .
Explanation:
In the product of two or more physical quantities , the number of places after decimal in the result can never be more than least number of place after decimal in the quantities that are being multiplied .
Here numbers that are being multiplied are ,
1.12 , 1.25, and .83 , each containing two digits after decimal . So the product can not contain more than two digits after decimal . The principle behind it is that the result can not have more precision than the precision of amount that are being multiplied.
so
1.12 x 1.25 x .83 = 1.162 to be rounded off to 1.16 .
The answer is 1.16.

Hmm...
dam power plant (not sure if this is considered renewable): benefits: as it creates a tourist spot bringing more money and provides electricity.
disadvantages: restricts flow of water to farms, costs millions to build.
solar power plant: benefits: sunlight just keeps coming, produces a lot of electricity for maybe half the cost.
disadvantages: takes a large crew to maintain, mostly needs to be in an open area.
Wind farm: benefits: wind we don't have to worry about much, just blows through and turns the turbines, and can produce electricity almost 24/7.
disadvantages: unsightly, needs open space and costs a lot to build
Take your pick!
