Question

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

Answer 1

Answer:

The volume of the sphere to the correct number of significant figures, which is 3 is 5.13 cm³

Explanation:

Diameter of the sphere = 2.14 cm

Radius of the sphere = 2.14/2 = 1.07 cm

We know that volume V of a sphere of radius R is given by

$V=\frac{4}{3}\pi r^3$

Putting the value of r we get

$V=\frac{4}{3}\times 3.1415\times (1.07)^3$

or, $V =5.1314$

∵ the number of significant figures in the diameter = 3

Therefore the answer must have 3 significant figures

Thus the volume of the sphere =5.13 cm³

Answer 2

Answer:

the volume of sphere is 5.13 CM cube
