The photo is an example.
Divide the diameter by 2 to get the radius.
Then times 1/3 time Pi times the radius squared times the height.
The formula is V=1/3(Pi)(radius squared)(height)
Y can be rounded up to 1.51 from a minimum value of 1.505
This is the lower bound.
y can be rounded down to 1.51 from a maximum value of 1.515
this is the upper bound.
y is between the lower bound and the upper bound so y is between 1.505 and 1.515
This is shown as 1.595<=y<1.515
<= is the typed out version of (greater than/equal to) which is < with a line under it.
75 ÷ 8 = 9
Remainder:- 3
So 8 goes in to 75 nine times with 3 left.
8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 72 OR 9 × 8 = 72.
SO,
8 goes into 75 nine times with 3 left.
Hope I helped ya!
A. If you draw the graphs you will find that B, C and D are all false.
The greatest common factor of

and

is
gcd(m*m*n*n, m*n*n*n) =m*n*n=

what we did, was to see how many m's and how many n's, each expression have, and then pick the smallest of each letter (factor).
the reason is that the common factor, must have enough m's and n's to divide the m's and n's of both expressions
so

also

thus, n is equal to 3
