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 =

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.
You may need to re-word that question for people to answer.
24x²-44x+12 = 4(2x-3)(3x-1)
<span>2x − 3
</span>
<span>Subtract 55 from 180 total degrees of a triangle to get 125.
Put 2x and x + 10 together...
3x + 10 = 125
Subtract 10 from both sides...
3x = 115
Divide by 3...
x = 38.3333
Now to find the measure of angle 2...
38.333(2) = 76.66666
Don't know if that's a multiple choice question or not, but that's what I got</span>
