The volume of a cone is 16 pi cubic inches its height is 12 iches. What is the radius of the cone? 2 inches 4 inches 12 inches 16 inches HELP PLEASE

The radius of cone is 2 inches  

Solution:

The volume of cone is given by formula:

Where,

"V" is the volume of cone

"r" and "h" are the radius and height of cone respectivel

Given that, volume of a cone is 16 pi cubic inches  

Its height is 12 inches  

Therefore, we get,  

V =  cubic inches

h = 12 inches  

r = ?  

Substituting the values in formula, we get    

Since, radius cannot be negative, ignore r = -2  

Thus radius of cone is 2 inches

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
