Cone-shaped 43291

Calculate the volume and weight of a pile of cone-shaped sand with a diameter of 8m and a height of v = 4.5m, the density of sand is 1500kg/M cubic

Correct answer:

V =  75.3982 m3
m =  113097.3355 kg

Step-by-step explanation:

D=8 m v=4.5 m r=D/2=8/2=4 m  V=31 π r2 v=31 3.1416 42 4.5=75.3982 m3
ρ=1500 kg/m3 m=ρ V=1500 75.3982=113097.3355 kg=1.131105 kg
