Question

A classroom globe has a diameter of 12 inches. What is the volume of the globe? Use 3.14 for pi. Round your answer to the nearest hundredth.

904.32 in3

2144.66 in3

7238.23 in3

9202.77 in3

Answer 1

The formula for the volume of a sphere is 4/3 x 3.14 x radius^3 
ince the diameter is 12, the radius would be half of it, or 6. So can you figure out 4/3 x 3.14 x 6^3?

The answer is 904.32

Answer 2

The volume of the globe is 904.32in³

The volume of the globe will be calculated by using the volume of a sphere and this will be:

= 4/3πr³

where,

π = 3.142

r = Diameter/2 = 12/2 = 6

Therefore, since we've the values, then we can slot it back into the equation and this will be:

= 4/3πr³

= 4/3 × 3.142 × 6³

= 4/3 × 3.142 × 216

= 904.32in³

Therefore, based on the calculation above, the volume of the globe is 904.32in³.
