$4 for one slice. divide amount paid by amount received to get the cost per item.
Area = pi radius squared. (a=pi r squared).
the radius of this circul is 1.6 units so plunging that in you get 1.6 • pie = 5.02654824574. now square that. The answer is 15.7913670417.
CALCULATE 5/8 + 3 1/4 x -3/6 - 2 5/12 = -3 5/12
V=hpir^2
r=2
h=5
pi≈3.141592
v=5*3.141592*2^2
v=5*3.141592*4
v=20*3.141592
v=62.83185307179586476925286766559
round to tenth
62.8 cubic units
Simplify it to 16a hope im right & hope this helps you .
