Answer 2

Answer:

Volume of sphere = 310464 cm³

                              = 310464 × 10⁻⁶ m³ = 0.310464 m³

Explanation:

We know that,

Volume of sphere = 4/3 πR³     where R is the radius of the sphere

Given that,

Diameter = 84cm

Radius = Diameter/2 = 42cm

Hence putting this value in we get,

Volume = 4/3 × 22/7 × 42³

             = 310464 cm³

             = 310464 × 10⁻⁶ m³ = 0.310464 m³
