Answer:
Step-by-step explanation:
The first thing we do to solve this is factor is completley
You can factor out a 4 from the numerator and get
4(3x+4)
The denominator is a difference of squares which means that
(x^2-y^2)=(x-y)(x+y)
which means that 9x^2-16=
(3x-4)(3x+4)
Put these together and get
The 3x+4 cancels out and we get left with
Answer:
236 cubic units (to 3 significant figures)
Step-by-step explanation:
volume of a cylinder = r²h (where r = radius and h = height)
Therefore, volume = x 5² x 3
= x 25 x 3
= 75
= 236 cubic units (to 3 significant figures)
