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.
Accepted Solution
A:
Answer:Volume of the sphere model of earth is 321m³Step-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 = 4.25mTherefore, imputing the parameters in the formular we have: ⇒4/3 × 3.14 × 4.25³ ⇒1.333 ×3.14 × 76.766Volume of the sphere model = 321.31m³ ≅ 321m³
