Answer:
Step-by-step explanation:
The formula for determining the volume of a hollow cylinder is expressed as
Volume = πh(r2² - r1²)
Where
h represents the height of the cylinder
π is a constant whose value is 3.14.
r1 represents the inner radius of the cylinder.
r2 represents the outer radius of the cylinder.
From the information given
h = 15
π = 3.14
r1 = 1 inches
r2 = 4 inches
Volume = 3.14 × 15 × (4² - 1²)
Volume = 706.5 inches²
