Answer:
2.4 lbs
Step-by-step explanation:
Firstly, we need to identify that a bowling ball is spherical in shape.
Hence, to answer this question at first, we need to know the volume of this bowling ball.
Since it is a sphere, the volume V = 4/3π [tex]r^{3}[/tex]
From the question, we are made to know that D = 4.5 inches, this means that r = D/2 = 4.5/2 = 2.25 inches
Substituting this into the equation of the volume, we have;
V = 4/3 ×π ×[tex]2.25^{3}[/tex] = 47.71 [tex]inch^{3}[/tex]
Now, we proceed to calculate the weight
Mathematically,
Weight = volume × density
Hence weight = 47.71 × 0.05 = 2.3855 lbs = 2.4 lbs to the nearest tenth
