An ice cream cone with a base 4.5 cm in diameter and whose height is 10 cm is filled with ice cream. What is the volume of ice cream to 3 d.p.? If the density of ice cream is 1095 kg/m^3, what is the mass of ice cream in 5 cones to 3 s.f.?
Volume of cone= 1/3Pihr^2 r=2.25 V=1/3Pi102.25^2=53.01 cm^3=5.301x10&-5 m^3 Mass=density*volume Mass=(5.301x10^-5)1095= 0.05805 kg Mass of 5= 0.058055=0.290 kg
