381.5 in3
972.1 in3
121.5 in3
3052.1 in3

Answer 1

Answer:

The Volume of globe would be 381.5 cubic inches if the dimensions of the globe was reduced by half.

Explanation:

$v=\frac{4}{3}$ × $3.14 x 4.5^{3}$

Radius is half of diameter

18÷2=9

radius=9in

Since the dimensions of the globe was reduced by half

radius=9÷2=4.5

$v=\frac{4}{3}$ × $3.14$ $4.5^{3}$

v= 4 × 3.14 × 30.375

v=12.56 x 30.375

v=381.51

v=381.5 in cubed
