Volume of Toy = Volume of Hemisphere + Volume of Cone.
=> Volume of Hemisphere = 2/3 × pie × r^3
=> = 2/3 × 22/7 × 7/2 × 7/2 × 7/2
=> = 1/3 × 11/7 × 49 × 7/2
=> = 0.33 × 1.57 × 49 × 3.5
=> = 88.85cm^3.
Volume of Cone= (pie × r^2 × h)/3
=> = (22/7 × 7/2 × 7/2 × 11)/3
=> = 3.14 × 3.5 × 3.5 × 3.66
=> = 140.78cm^3.
Therefore, Volume of toy =140.78 + 88.85
= 229.63cm^3.
