diameter of hemispherical part of the toy=14cm
radius of the hemispherical part of the toy=d/2=14/2=7cm
Total height of the toy=14cm
height of hemispherical part of the toy= radius of the hemispherical part =14cm
Therefore,
height of the conical part of the toy=total height of the toy - height of the hemispherical part of the toy=14-7=7cm
volume of the toy=volume of the conical part+ volume of hemispherical part=1/3πr²h +2/3πr³
=1/3πr²[h+2r]=1/3×22/7×7×7(7+2×7)=1078cm³
HOPE IT IS CORRECT. IF IT CORRECT THEN PLZZZ MARK IT AS BRAINLEIST.
