Question

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.

Answer 1

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
