The radius of cone is: 3 inches
Step-by-step explanation:
Given
Volume of cone = V = 141.3 cubic inches
Height = h = 15 inches
We will use the formula for volume of cone to find the radius of cone
The formula for volume of cone is:
[tex]V = \frac{1}{3}\pi r^2h[/tex]
Putting the value
[tex]141.3 = \frac{1}{3} * 3.14*r^2 * 15\\141.3 = 5*3.14*r^2\\141.3 = 15.7r^2\\r^2 = \frac{141.3}{15.7}\\r^2 = 9[/tex]
Taking square root on both sides
[tex]\sqrt{r^2} = \sqrt{9}\\r = 3[/tex]
The radius of cone is: 3 inches
