Answer:
225 children
Step-by-step explanation:
d = 1.4 m = 140 cm, r=70 cm
ht = 56cm
Volume of food in 3 such containers= 3( πr^2h)
=3 * π*70*70*56
radius of hemispherical bowl= 14cm (Two servings)
Volume of 2 hemispherical bowls=volume of 1 spherical bowl= 4/3 π r^3
No of children served = Volume of containers divided by volume of 2 servings
= 3* π* 70 * 70 * 56 divided by 4/3 * π* 14*14*14
= 225
