Answer:
4778.4 cm³
Explanation:
The formulae of finding the volume of a cone = 1/3 * π * r² * h
(r = radius; h = height)
Therefore replacing the variable with values gives = 1/3 * π * 13² * 27
= 4,778.3624261100755157016805859681
Volume to the nearest tenth = 4778.4 cm³

<h3>What is way of testing medicines?</h3>
In a laboratory, drugs are first subjected to non-human tests. These laboratory tests are performed to determine a level of safety.
The results of these tests are then submitted to the United States Food and Drug Administration (FDA), which determines whether the treatment is safe enough to be studied in human volunteers.
There are various phases involving discovery, clinical trial, review, and safety monitoring.
