Answer:
Step-by-step explanation:
as ice cream tofilled so voume of bot will be same
volume of cylinder = no of cones n (volume of cone + volume of hemisphere)
πR²H = n((1/3)π r² h + (2/3)πr³)
π6² *15 = n((1/3)π 3² 12 + (2/3)π3³)
1697.1 = n * 169.71
n = 10
Answer:
10
Step-by-step explanation:
(i)
Height of cylindrical container(h₁) = 15 cm.
Radius of circular end of container(r₁) = 12/2 = 6 cm.
Volume of right circular cylinder:
= πr₁²h₁
= π(6)² * 15
= 540π
(ii)
Height of conical part of ice-cream cone(h₂) = 12 cm.
Radius of circular end of ice-cream cone(r₂) = 6/2 = 3 cm.
Volume of ice-cream cone including hemispherical top:
= [1/3 π r₂² h₂ + 2/3 πr₂³]
= [1/3 π (3)² * 12 + 2/3 π (3)³]
= [36π + 18π]
= 54π cm³
∴ Required number of ice-cream cones = 540π/54π
= 10.
Therefore, 10 ice-cream cones can be filled with the ice-cream.
Hope it helps!
