The diameter of a cylindrical construction pipe is 4ft . if the pipe is 20ft long, what is its volume

Volume = π (2ft)² (20ft) = 80 π ft² ≈ 251.3 ft²

Explanation:

1) Formula

Volume of a cylinder = area of the base × length

Area of the base = π r²

r = diameter / 2

2) Calculations:

r = 4 ft / 2 = 2 ft

length = 20 ft

Volume = π (2ft)² (20ft) = 80 π ft² ≈ 251.3 ft²

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
