B. 102.57 cu. cm is the answer
Solution:
V=πr^2h
The diameter is 14. To find the radius you divide the radius by 2 which is equal to 7. [Radius is 2 times diameter]
V= 3.14×7×7×2
V= 102.57

x^3+7^3=(x+7)(x²-7x+49) A: False (+14)
x^3+8^3=(x+8)(x²-8x+64) B:False (+8x)
x^3-10^3=(x-10)(x²+10x+100) D:False (-10x)
Step-by-step explanation:
a).
n! is
(n-3)! is
If we divide the two, everything behind (n-3) will just cancel out so we would be left with only
So the answer to a is
b
Permutations formula of P(6,4) is
6!/(6-4)!, or 6!/2!.
Then we divide by 4!
The answer to b is 15
125=5 packets of pencils
each package contains 8 red
5 packages contain 5×8=40
In 125 pencils 40 are red.
