Question

which unit of measure would be appropriate for the volume of a sphere with a radius of 2 meters? a. centimeters b. meters c. square meters d. cubic meters

Explanation:

To determine the appropriate unit for the volume of a sphere, we recall the concept of volume units. Volume measures the amount of space an object occupies, and for three - dimensional objects, the unit of volume is a cubic unit.

• Option A: Centimeters is a unit of length, not volume, so it is incorrect.
• Option B: Meters is also a unit of length, not suitable for measuring volume.
• Option C: Square meters is a unit of area (used for two - dimensional measurements like the area of a surface), not volume.
• Option D: Cubic meters is a unit of volume, as volume of a three - dimensional object is calculated by multiplying three length measurements (e.g., for a rectangular prism \(V = l\times w\times h\), the unit would be \((\text{unit of length})^3\)). For a sphere with radius measured in meters, the volume will be in cubic meters.

Answer:

D. Cubic meters
