Answer:
Yes
Step-by-step explanation:
Circumference formula is C=2 pi r, if you divide the pizza by 2 to get the radius,5, then input it into the formula to get 31.41592654, and since this number is smaller than 32 it will fit. If 10 is the radius it will not fit.
 
        
             
        
        
        
Answer:
x^2\ 16 - y^2/9 = 1 
step-by-step explanation:
soooo the equation for a hyperbola that is horizontal is x^2/a^2 - y^2/b^2 = 1 
a hyperbola should always equal one so dont forget that when writing your equation becuase it is easy to forget. 
it helps to graph this so you can see it better 
to find a it is the distance from the center to the vertices which is 4 so in the equation you will write 16 becuase it is a^2 
then you need to find b. to get b you have to figure out that c is the distance from the center to the foci which is 5 and it is all related to the plythagorm theorum becuase it forms a right triangle. so you do c^2 - a^2 = b^2 
you get 9 for b^2 because 25-16=9 and so you put that in the equation
