Aglobe company currently manufactures a globe that is 18 inches in diameter. if the dimensions of the globe were reduced by half, what would its volume be? use 3.14 for π and round your answer to the nearest tenth.
a.381.5 in3
b.972.1 in3
c.121.5 in3
d.3052.1 in3

answer: option a

step-by-step explanation:

the current diameter of the globe is:

if the dimensions were reduced by half then the diameter would be:

so the radius r is:

assuming the globe is spherical, then the formula for calculating the volume of a globe is:

so

3-4
