3 The volume of a cylinder is given by V = nr4h,
where r is the radius of the cylinder and h is the
height. Which expression represents the volume
of this can?
* 371x2 + 471X + 161
Зах? +16л
* 37x +324
37X+20xX? +447x +32

3πx³ + 20πx² + 44πx + 32π

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

r = radius of the cylinder

h = height of the cylinder

r = x+2

h = 3x + 8

Volume of a cylinder = πr²h

= π × (x+2)² × 3x + 8

= (3xπ + 8π) × (x + 2)²

= (3πx + 8π) + (x² + 4x + 4)

= 3πx³ + 12πx² + 12πx + 8πx² + 32πx + 32π

= 3πx³ + 20πx² + 44πx + 32π

Note:

(x + 2)²

= (x + 2) (x + 2)

= x² + 2x + 2x + 4

= x² + 4x + 4

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
