Question

Find the amount of water displaced by a solid spherical ball of diameter
(i) 28 cm
(ii) 0.21 m​

Answer 1

Answer:

1. with radius 14 cm ,

volume of sphere = 4 /3 πr cube

= 4 / 3 × 22 / 7 × 14 × 14

= 4 / 3 × 22 × 2 × 14

= 4 / 3 × 44 ×14

= 44×4 × 14 ÷3

= 821.33 cm cube

Answer 2

Answer:

r = 28/2 i.e. 14

Step-by-step explanation:

volume of sphere is 4/3

$4 \div 3\pi r {}^{2}$

now,

1. 4/3*22/7*14*14
2. 264/3
3. answer = 88 cm3
