Volume = base area * height. Base area = πr^2 = 1/4 * π (diameter)^2 = 9π.
Height = volume / base area = 9.6.
Plug your input (m) into the equation given. Then complete you table.
Answer:
5:2

20:8
Is this what format you wanted the answer?
Step-by-step explanation:
82.300 * x percent = 69.955
To solve this equation you have to transpose it:
x percent = 69.955/82.300 = 0,85 = 85%
That's the percentage of 69.955 of 82.300.
So the last step is to subtract it from 100%:
100% - 85% = 15 % --> percent of decrease
