Suppose y varies jointly as × and z. What is y when × = 2 and z = 3, if y = 20 when × = 4 and z = 3?
1 answer:
Answer:
y = kxz
Step-by-step explanation:
(Find K)
20 = k(4) (3)
20/12 = k
k = 5/3
(Find Y)
y = (5/3)(2)(3)
y = 10

Step-by-step explanation:
Formula
V = pi * r^2 * h
Givens
h = 22 cm
r = d/2 = 7/2
r = 3.5
pi = 3.14
Solution
V = 3.14 * 3.5^2 * 22
V = 846.23 cm^3
The answer is B.
