Question

an 11 pound bowling ball has a circumference of 27 inches. calculate the density of the bowling ball and determine whether it will float or sink if placed in water. ignore the holes in the bowling ball

Answer 1

Answer:

The density is 0.0036023 pounds/inches³, which is 99.71 kg/ m³. The ball will float.

Explanation:

Density is mass/ volume.

The mass is 11 pounds.

Calculate the volume of a sphere by using $\frac{4}{3}$πr².

V =$\frac{4}{3}$π(27)²

V = 3053.63 inches³

Density = mass/volume

Density = 11 pounds/ 3053.63 inches³

Density = 0.0036023 pounds/inches³

Convert this to kg/ m³, which is 99.71 kg/ m³. Water has a density of 1000 kg/m³. Since the ball has a lower density than water, it will float
