Answer:
1139.82
Step-by-step explanation:
3.14×5.5×5.5×12= 1139.82
5.5×5.5=30.25
30.25×12=363.00
363×3.14=1139.82

1-.80=.20
.20=20%
Explanation:
To find x we need to find the unknown side that connects the two triangles using the Pythagorean theorem:
a² + b² = c² (c is always hypotenuse)
So:
a² + 6² = 9²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = sqrt45
Now we do the same thing for the other triangle:
x² + 5² = sqrt45²
x² + 25 = 45
x² = 20
x = 2√5 or 4.5...
