Answer:
The volume of item described = 52π
Explanation:
Formula:-
Volume of cone = 1/3(πr²h)
Volume of hemisphere = 2/3(πr³)
Where r is the radius and h height
It is given that,
An ice cream cone with a cone of radius 2 cm and height of 9 cm with a hemisphere of ice cream on top of radius 2 cm
To find the volume of cone
r = 2cm and h = 9 cm
Volume = 1/3(πr²h) = 1/3(π*2²*9) = 12π
To find the volume of hemisphere
r = 2 cm
Volume = 2/3(πr³) = 2/3(π*2³) = 16/3 π
To find the total volume
Total volume = volume of cone + volume of hemisphere
Total volume = 12π + 16/3 π = 52π/3
Therefore the correct answer is 52π/3
