Answer:
A
Step-by-step explanation:
Given the 2 equations
4x + 5y = - 12 → (1)
- 2x + 3y = - 16 → (2)
Eliminate the x- term by multiplying (2) by 2 and adding the result to (1)
- 4x + 6y = - 32 → (3)
Add (1) and (3) term by term
11y = - 44 ( divide both sides by 11 )
y = - 4
The unfilled volume inside the cylinder is determined as 640π cubic units.
<h3>
Volume of the cylinder</h3>
The volume of the cylinder is determined as follows;
V = πr²h
where;
- r is radius of the cylinder given as 8 units
- h is height of the cylinder determined as 15 units
V = π(8²)(15)
V = 960 π cubic units
<h3>Volume of cone</h3>
V = ¹/₃πr²h
where;
- r is radius of the cone given as 8 units
- h is slant height of the cone determined as 15 units
V = ¹/₃π(8)²(15)
V = 320 π cubic units
<h3>Unfilled volume of the cylinder</h3>
ΔV = 960 π - 320 π = 640 π cubic units
