Answer:
Step-by-step explanation:
If you had a solid cylinder, in order to find the amount of material that makes up that solid cylinder, you would find the volume using the radius of 4 (half of the diameter 8). BUT we want to know the volume of the solid with the radius of 4 minus the solid that has a radius of 2.5 (half of the diameter 5).
That's volume outer - volume inner. To find the outer volume:
so
and
and do the same for the inner volume:
and

Subtract the inner from the outer:

If you need your answer in decimal form, then the volume is
9189.16 cm³
I thank is 156
Step-by-step explanation:
16=48x-6y
swap the sides of the equation
48x-6y=16
Divide both sides of the equation by 2
24x-3y=8
now we do the same only different way ok
48x-6y=16
Divide both sides of the equation by 2
(48x-6y)÷2=16÷2
Distribute 2 through the parentheses
48x÷2-6y÷2=16÷2
calculate the quotient
48x÷2-6y÷2=8
calculate the quotient
24x-6y÷2=8
calculate the quotient
Answer: 24x-3y=8

Answer:
Yes
Step-by-step explanation:
There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.
