Answer:

The height is 8 inches

Step-by-step explanation:

Well to find the volume of a cylinde like this, he formula is Base * height.

To find the base we need to find the area of the circle.

a=πr^2

The radius is 3 inches, 3^2=9

Since π is suppose to be 3.14 multiply

9*3.14= 28.26

We know that the cylinder can hold 231 cubic inches. So technically it can fill (x) 28.26 inches.

solve the equation

28.26x=231

Divide

231/28.26

The answer would be about 8 inches

2y= 13 -7

2y = 6

divide both sides by 2

2y/ 2y = 6/2

y= 3
