The radius of cone is 2 inches
<em><u>Solution:</u></em>
<em><u>The volume of cone is given by formula:</u></em>
Where,
"V" is the volume of cone
"r" and "h" are the radius and height of cone respectively
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 = ?
<em><u>Substituting the values in formula, we get</u></em>
Since, radius cannot be negative, ignore r = -2
Thus radius of cone is 2 inches
Step-by-step explanation:
<u>Step 1: Distribute</u>
<u>Step 2: Add 6 to both sides</u>
<u>Step 3: Subtract 2x from both sides</u>
<u>Step 4: Divide both sides by 10</u>
Answer:
D.
Por álgebra, recordamos los siguientes dos teoremas llamados teorema del signo para productos:
,
(1)
,
(2)
Basados en la información dada en la imagen y los teoremas descritos arriba, el producto del numerador debe ser negativo y el producto del numerador debe ser también negativo, más el resultado de la división debe ser positiva.
Por tanto, la opción D representa a la operación libre de errores.
