Answer:

Step-by-step explanation:

Part of the definition of a polynomial is that the exponents have to be non-negative integers. In other words, it cannot have a fraction as an exponent or an imaginary number. Our polynomial has real non-negative exponents, so it is in fact a polynomial. The degree is found in the highest exponent of the polynomial. Ours is a 5th degree. The leading coefficient is the number stuck to the x that has the highest degree. Therefore, our leading coefficient is -16. B is your choice.

If a large cylinder has a volume of 28260 cubic cm, how many cylinders can be filled out of the large cylinder if the small cyli

inysia [295]

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.
