Answer:
Volume of the sphere model of earth is 321m³
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
