Answer: 10 inches.
Step-by-step explanation:
Since the pecan pie is a circle, you can use this formula:

Where "r" is the radius and
is the central angle of the arc in radians.
If the pecan pie has been cut into 8 equal pieces then the central angle is:

Now you know the arc length and the central angle, then, you can solve for "r" from
:

Substituting values, you get that the radius of the pecan pie rounded to the nearest whole number is:

Answer:
110 grams
Step-by-step explanation:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams.
