Answer:
142.4 Cubic units
Step-by-step explanation:
V=1/3pir^2h
V=1/3(pi)(4^2)(8.5)
V=142.418866963
The angles in an equilateral triangle are 60 degrees.
sin 60 = 9 / h where h is hypotenuse ( = side of the triangle)
h = 9 / sin 60 = 10.392
Perimeter = 3 * h = 31.18 to nearest hundredth
If what you mean is what does x equal then X=30
