Answer:
Their combined height is 108 inches
Step-by-step explanation:
1 ft = 12 inches
12 * 4 = 48 inches
48 + 6 = 54 inches
54 * 2 = 108 inches
Volume of the cylinder=area (circle) x height
1) we calculate the area of the circle.
area of the circle=πr²
r=13 in.
area of the circle=π(13 in)²=169π in²
2) we calculate the volume of the cylinder:
area (circle)=169π in²
height=30 in
volume=169π in² x 30 in=5070π in³ ≈ 15927.87 in³
Answer: 5070π in³ or 15927.87 in³
Answer:
Step-by-step explanation:
we know that
The total surface area of a cylinder is equal to
where
r is the radius of the base of cylinder
h is the height of cylinder
we have
----> the radius is half the diameter
assume
substitute the given values and solve for h
Solve for h
