Answer:
The answer to your question is: 6 units
Step-by-step explanation:
Data
height = 3r
Volume = 24 u³
Volume = 1/3 πr²h
Process
24 = 1/3 (3.1416)(h/3)² (h)
72 / 3.1416 = h³/9
22.91 x 9 = h³
206.26 = h³
h =5.9 u ≈ 6 u
M = - 1/5
y = m x + b
7 = - 1/5 · ( - 3 ) + b
7 = 3/5 + b
b = 7 - 3/5
b = 35/5 - 3/5
b = 32/5
The equation is:
y = - 1/5 x + 32/5 or : y = - 0.2x + 6.4
