Answers
Answer:
father Suresh got more quantity of juice by 13.5π cm3
Given –
radii of both glasses r = 3 cm
heights of both glasses h = 10 cm
height of conical bottom h’ = 1.5 cm
To find – difference between volumes of juice in two glasses
Formulae –
1. Volume of cylinder
2. Volume of hemisphere
3. Volume of cone =
Answer –
Volume of juice in first type of glass
V1 = volume of cylindrical glass – volume of hemisphere
∴ V1 = 90π - 18π
∴ V1 = 72π cm3
Now, volume of juice in second type of glass
V2 = volume of cylindrical glass – volume of cone
∴ V2 = 90π – 4.5π
∴ V2 = 85.5π cm3
Therefore, second glass will contain more amount of juice.
The difference in volumes of juice in two glasses is
∴ V2 – V1 = 85.5π - 72π = 13.5π cm3.
Hence, father Suresh got more quantity of juice than Isha by 13.5π cm3.
