Question

A cylindrical jar of radius 6 cm contains water. How many iron spheres each of radius 1.5 cm are required to raise the level of water by 2 cm?​

Answer 1

Heyy

Here is you answer

Given

r1 = 6cm

r2 = 1.5cm

height = 2cm

πr^21 h1 = n4/3 πr^32

n = 3r^2 1 h1 / 4r^3 2

n=3×6×6×2 / 4×1.5×1.5×1.5

∴n=16 sphere
