Hi,

To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:

$v = \pi \times {r}^{2} \times h$

To find radius just divide diameter with 2.

$v = \pi \times {2}^{2} \times 6 \\ v = \pi \times 4 \times 6 \\ v = \pi \times 24 \\ v = 3.14 \times 24 \\ v = 75.4 {cm}^{3}$

Now just division:

$28260 \div 75.4 = 374.8$

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.

Hope this helps.

I need help with this problem. please help

Answer:

$y = 46x + 0$

Step-by-step explanation:

The equation of a line follows the following format

$y = mx + c$

Note m= the gradient of the line or the slope of the line. To find the gradient it is

$m = \frac{rise}{run}$

On this graph the

$rise \: = 460 \: \\ and \\ run = 10 \\ \\ m = \frac{460}{10} \\ m = 46$

After finding the gradient we can now find the equation of the line. We can use any point on the line in order to do this, in that case lets use the point (10, 460)

$y = 460 \: \: \: \: \: \: x = 10 \: \: \: \: \: m = 46\\ y = mx + c \\ 460 = (46)(10) + c \\ 460 = 460 + c \\ 460 - 460 = c \\ 0 = c$

$y = 46x + 0$
