Step-by-step explanation:

Volume of article=volume of cylinder-(volume of cone+volume of hemisphere)
Volume of article=volume of cylinder-(volume of cone+volume of hemisphere)Volume of cylinder=>`pir^2h=22/7xx7xx7xx40=6160(cm)^2`
Volume of article=volume of cylinder-(volume of cone+volume of hemisphere)Volume of cylinder=>`pir^2h=22/7xx7xx7xx40=6160(cm)^2`volume of hemisphere=`2/3pir^3=2/3xx22/7xx7xx7xx7=718.6(cm)^3`
Volume of article=volume of cylinder-(volume of cone+volume of hemisphere)Volume of cylinder=>`pir^2h=22/7xx7xx7xx40=6160(cm)^2`volume of hemisphere=`2/3pir^3=2/3xx22/7xx7xx7xx7=718.6(cm)^3`volume of cone=`1/3pir^2h=1/3xx22/7xx7xx7xx24=1232(cm)^3`
