The formula for determining the volume of a cone is expressed as
Voume = 1/3 x pi x radius^2 x height
From the information given,
volume = 20
height = 15
we know that pi = 3.14
Thus, we have
20 = 1/3 x 3.14 x radius^2 x 15
20 = 15.7 x radius^2
radius^2 = 20/15.7 = 1.274
[tex]\begin{gathered} \text{radius = }\sqrt[]{1.274} \\ \text{radius = 1.13} \end{gathered}[/tex]The radius of the cone is 1.13 inches
