Answer:28.26
Step-by-step explanation:kid use pi r^2
7200 kg = 7.200.000 grams because 1 kg is 1000 grams
Triangle on the right is 30 60 90 triangle
The ratio of short leg : long leg : hypotenuse = a : a√3 : 2a
Given long leg = 8√2
so short leg = 8√2 / √3 = 8√2 *√3 / √3 *√3 = 8√6/ 3
Hypo = 2 (8√6/ 3) = 16√6/ 3
The triangle on the left is 45 45 90 triangle
Ratio of leg : hypotenuse = a : a√2
The hypotenuse of triangle on the right is the leg of triangle on the left
so a = 16√6/ 3
Hypotenuse, x = (16√6/ 3) √2 = 16√12 / 3 = 32√3 / 3
Answer is B.
32√3 / 3

1. No solutions
2. Many solutions
3. No solutions
4. One solution
5. Many solutions
Answer:
1) 
2) 
3) 
4) 
Step-by-step explanation:
1) Value of 
since sin45° = 1/√2
Therefore
2).Value of 
Since cos 30° = √3/2
Therefore
3). Value of 
since tan 60° = √3
therefore
4). Value of 
Since sin90°=1
Therefore
