Question

the diameter of a sphere is 2.14cm calculate the volume of sphere to correct number of significant figures ​

Answer 1

Answer: 5.13

Explanation:

Diameter (d) = 2.14

Radius (r) = 2.14/2 = 1.07

Volume of sphere = 4/3πr3 =4/3*3.14*1.07*1.07*1.07

=5.13

Answer 2

Answer :

Given,

the diameter of the sphere = 2.14 cm

Then, its radius = (2.14/2) cm = 1.07 cm

Hence, its volume is

= 4/3 πr³ , where r = radius

= 4/3 * 22/7 * 1.07³ cm³

≈ 5.13 cm³ (approximately)
