Question

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

Answer 1

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:

$V=\dfrac{4}{3}\pi r^3$

Substitute r=0.5 and $\pi=3.14$ to find the volume of the fishing bobber.

$V=\dfrac{4}{3}(3.14)(0.5)^3$

$V=\dfrac{4}{3}(3.14)(0.125)$

$V=0.52333...$

Approx the value to the nearest tenth.

$V\approx 0.5$

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