Answer:
The volume of the pipe is 239 ft³
Step-by-step explanation:
The rule of the volume of a cylinder is V = π r² h, where
- r is the radius of its base
∵ The diameter of a cylindrical construction pipe is 4 ft
∵ The radius is half the diameter
∴ r = × 4 = 2 ft
∵ The pipe is 19 ft long
∴ h = 19 ft
∵ π = 3.14
→ Substitute them in the rule of the volume
∴ V = 3.14(2)²(19)
∴ V = 238.64 ft³
→ Round it to the nearest whole number
∴ V = 239 ft³
∴ The volume of the pipe is 239 ft³

Answer: 384
Step-by-step explanation:
4/100×3200×3yrs
=128
Answer:
step 1. The vertex is when x = -b/2a (by definition)
step 2. a = -16, b = 15. x(vertex) = -15/2(-16) = 15/32
step 3. y(vertex) = -16(15/32)^2 + 15(15/32) = 225/64 = 3 33/64
step 4. since the ball started at a height of 5 feet you add 5.
step 5. answer: 3 33/64 + 5 = 8 33/64.
