Whats the volume of a cylinder that’s has a 3in radius and 12 in hight

the volume of the cylinder is 4

Step-by-step explanation:

12 divided by 3 equals 4

V≈339.29

Step-by-step explanation:

You are given:

Radius= 3

Height= 12

Use formula for volume of cylinder,

V=πr^2h

V=3.14 * 3^2 * 12

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
