Part A : formula for circumference = pi*D or 2piR
for circle A.... 8*pi=25.12
therefore pi=3.14
for circle B.... 3*pi=9.42
therefore pi=9.42/3
pi=3.14

part B : formula for Area =
$pi \times {r}^{2}$
for circle A.... 50.24=pi*(8/2)sqr...(because diameter/2= radius)
pi=50.24/16
pi=3.14

for circle B... 7.065=pi*(3/2)sqr...
pi=7.065/2.25
pi=3.14

what do you observe?
the values for pi are all equal... therefore pi is constant.

The difference between a number and 7 is greater than -23

Aleks04 [339]

-23 is a negative number so that means 7 is a greater number. any number with a minus sign like this - means it’s a negative number, so any number that you have to compare it to and if that number has nothing before or after it, then that would be the greater number

Help, I cant understand!!!

These problems are what is known as changing a mixed fraction to an improper fraction. Lets start with 5 1/8.

What we want to do is take the big number on the side and add it to the top of the fraction in a special way to make it an improper fraction. (An improper fraction means a fraction with a bigger top than bottom).

To add 5 to 1/8, we have to multiply 5 by 8 and then add it. 5 times 8 is 40 so if we add that to the top we know that the improper fraction we are looking for is 41/8.

We can do the same thing for 3 4/12, multiply 3 by 12 and add it to the top of the fraction. 3 times 12 is 36, add that to the top to get 40/12.

See if you can do 1 6/12 and comment with an answer, if you get it wrong I will keep helping you till we get this down!
