Answer:
y = 1/9 x z^3
Step-by-step explanation:
y is jointly proportional to x and z^3
y = k * x * z^3 where k is the constant of proportionality
y =12, x = 4 and z =3
12 = k * 4 * 3^3
12 = k * 4 * 27
12 = k * 108
12/108 = k
1/9 = k
y = 1/9 x z^3
You would have to multiply 3.14x29.8 which is 93.572, or 93.6 to the nearest tenth
You would do 60 times 11. 60 times 11 equals 660 that is the answer
