a cylinder tub of radius 5 cm and length 9.8 cm is full of water. a solid in the form of a right circular cone mounted on a hemisphere is immersed into tub. if the radius of hemisphere is 3.5 cm and height of cone outside the hemisphere is 5 cm find volume of water left in the tubplz ans quickly​

Answer»

Answer:●volume of cylinder=T| r²h=22/7×5²×9.8=770cm³

●volume of hemisphere=2/3 T| r³=2/3×22/7×3.5²=89.83cm³

●volume of cone=1/3T| r²h=1/3×22/7×3.5²×5=6.41cm³

●TOTAL volume of solid=volume of cone+volume of hemisphere=89.83+6.41=96.24cm³

●now, total volume of water LEFT in the cylinder=volume of cylinder-volume of solid=770-96.24=673.76cm³....

EXPLANATION:note that T| is actually a pie....try to understand it.....hope it will HELP you:)
