Answer» Let radius of cone, R = 2.5 cm, radius of shots, r = 0.25 cm,height of cone, H = 11 cm, Number of lead shots = n.Volume of n shots = volume of water that flows outn×4/3πr^3 = 2/5×1/3πR^2Hn = (2/5×1/3πR^2H)/(4/3πr^3)= (2R^2H)/(5×4r^3)= [2×(2.5 cm)^2×11 cm]/[5×4×(0.25 cm)^3]= [(2×25×25×11)/100]/[(5×4×25×25×25)/1000000]= (22×10000)/(500) = 440. |
