A: 37.68
B: 6.28
C: 18.84
D: 12.56

D

Step-by-step explanation:

(1/3) * π * 2^2 * 3 = 4π = 12.56

D

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
