Respectfully, I beg to say that my father is a government servant. He has been transferred to Mumbai. So, I cannot continue my study here.
I, therefore, request you to issue me a school leaving certificate so that I may join the new school there.
Thanking you,
Answer:
in cylinder
diameter is 12 cm
hence radius will be 6cm
height is 15 cm
volume of cylinder is
πr^2h
π ×6×6×15 cm ^3
now, volume of 1 toy
2/3 × πr^3 + 1/3 πr^2 h
1/3 πr^2 ( 2r + h)
height of cone is 3 times r
h = 3r
as 12 toys were recasted..
volume of 12 toys = volume of cylinder
12 ×1/3 πr^2 ( 2r + h) = πr^2h
4 πr^2 ( 2r + 3r ) = π ×6×6×15
4 r^2 (5r) = 6×6×15
r^3 = 6 ×6×15/4×5
r ^3 = 3 ×3×3
r = 3 cm
radius of sphere is 3 cm
height of conical part is 3 ×3 = 9 cm
height of toy is 3 +9 = 12cm
