i dont know the answer im in nursery
Step-by-step explanation:
The total volume is the sum of volume of cone and volume of cylinder.
Volume of cylinder = πr²h
π = 3.14
r = 4/2 = 2 mm
h = 2 mm
So, volume of cylinder equals:

mm³
Volume of cone =

π = 3.14
r = 2 mm
h = 3 mm
So, volume of cylinder equals:

mm³
Thus, total volume of the figure = 25.12 + 18.84 = 43.96 mm³
Answer:
Step-by-step explanation:
f(x) = -8x² + 7x³ + 2x - 5
= 7x³ - 8x² + 2x - 5 This meets the definition of a polynomial
Answer:
It is A.
Step-by-step explanation:
To solve for b, use the 45-45-90 triangle theorem, in which each of the legs is x, so the legs would be 8. The hypotenuse would therefore be 8√2.
So without further solving the answer is A, since it's the only one with 8√2.
However, I will still solve for A and C. Using the 30-60-90 theorem, we have the sides as x, x√3, and 2x. The second longest side is b. Using this, we find a = 4√6 and c to be 4√2
So all positive integers is the domain (the number you can use)
and the range (the numbers you get when you put the numbers in the domain in) is all positive integers more than 2
