Always use your imaginary scissor:
Cut the above and below circle and the cylinder role it down-ways like a carpet and you will end up with two circles and a big rectangular.
Surface circle: 7 * 7 * 3,14 = 153.86
Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7

Answer:
90 g of water should be added and he will make 900 g of solution.
Step-by-step explanation:
Let x g be the amount of salt Ilya add to 810g of water to make 10% solution. Then 810+x g is the amount of new solution. Thus,
810+x - 100%,
x - 10%.
Mathematically,
So 90 g of water should be added and he will make 810+90=900 g of solution.
