Answer:

5572.45

Explanation:

the formula to calculate the colume of a sphere is (4/3)πr², where r is the radius of the sphere.

to find r (radius):

- divide the diameter by 2 because d = 2r, where d is the diameter and r is the radius

r = 22/2

= 11 in

to find volume of the globe:

- substitute r = 11 into (4/3)πr³

v = (4/3)π(11)³

= 5324π/3

≈ 5575.27976 in³

hence, the best approximation of the globe is 5572.45 in³.
