. A fishing bobber has a radius of 0.5 inch. Find the volume of the fishing bobber. Round your answer to the nearest tenth.

Sagot :

Given:

The radius of the fishing bobber = 0.5 inch.

To find:

The volume of the find bobber.

Solution:

We know that the shape of fishing bobber is a sphere.

The volume of a sphere is:

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Substitute r=0.5 and [tex]\pi=3.14[/tex] to find the volume of the fishing bobber.

[tex]V=\dfrac{4}{3}(3.14)(0.5)^3[/tex]

[tex]V=\dfrac{4}{3}(3.14)(0.125)[/tex]

[tex]V=0.52333...[/tex]

Approx the value to the nearest tenth.

[tex]V\approx 0.5[/tex]

Therefore, the volume of the fishing bobber is 0.5 cubic inches.
