Question

Volume of sphere to currect no. Of significant figurees its diameter is 2.14 cm

Answer 1

Volume of a sphere = $\frac{4}{3} \pi r^{3}$

Diameter of the sphere = 2.14 cm

Radius of the shpere= 1.07 cm

$\pi$ = 3.14

$\frac{4}{3}$ × 3.14 × (1.07)³ = 5.13 cm³

∵ the diameter of the sphere has 3 significant figures, the answer will also have 3 significant figures.

∴ the volume of a sphere with a diameter of 2.14 cm = 5.13 cm³
