Answer:
Height of the goalpost is 9.25 m.
Step-by-step explanation:
As per the rule of reflection in physics,
Angle of incidence = Angle of reflection
As we can see in the picture attached, both the angles (θ) are equal.
m∠ACB = m∠ECD = 90° - θ
m∠ABC = m∠ADC = 90°
Therefore, both the triangles ΔABC and ΔEDC will be similar.
And by the property of similar triangles, their corresponding sides will be proportional.


ED = 
ED = 9.25 m
Height of the goalpost is 9.25 m.
The fraction 4/6 could represent the green
Answer:
3617.28 mm³
Step-by-step explanation:
The volume of a cylinder is...
V = πr²h
Plug in the values given into the equation
V = (3.14)(12²)(8)
V = (3.14)(144)(8)
V = 3617.28 mm³
