its none of them? 6y - 10/5 +7y = 12 10 divided by 5 equals 2

it will now look like this: 6y - 2 + 7y = 12

then your going to want to add 2 to both sides of the equation.

it will now look like this: 6y -2 + 7y + 2 = 12 + 2 = 14

simplify: 6y + 7y = 14

add the like terms: 13y = 14

Answer:

A. $V = (pi)(3.25)^2(12)$

Step-by-step explanation:

The formula for the volume of a cylinder is the formula for the area of the circle, times the height of the cylinder. The formula for the volume of a circle is,

$A = (pi)(r)^2$

Multiply that by the height to find the formula for the volume of a cylinder,

$V=(pi)(r)^2(h)$

Where (pi) represents the value (3.1415), (r) represents the radius, and (h) represents the height of the cylinder. Now substitute in the given values, remember, this problem gives the diameter of the cylinder, divide that value by two to find the radius.

$V=(pi)(\frac{6.5}{2})^2(12)\\\\V = (pi)(3.25)^2(12)$
