2. a science museum has a spherical model of the earth with a diameter of 8.5 m. what is the volume of the model? use 3.14 for and round your answer to the nearest whole number. show your work.

Volume of the sphere model of earth is 321m³

Step-by-step explanation:

Parameter given:

    diameter of the sphere = 8.5m

      π = 3.14

   Volume of a sphere is given as = 4/3 π r³

      Where r is the radius of the sphere.

  From given diameter, radius = 8.5/2 = 4.25m

Therefore, imputing the parameters in the formular we have:

                           ⇒4/3 × 3.14 × 4.25³

                            ⇒1.333 ×3.14 × 76.766

Volume of the sphere model = 321.31m³ ≅ 321m³
