Answer:
(A) Pi cannot be written as a ratio of integers even if it represents a different ratio.
Step-by-step explanation:
A rational number is can be expressed as the quotient of two integers. It can either be a number with or without a decimal part when converted to decimals.
C = 2
r and D = 2r

Terrence was incorrect because Pi is an irrational number which cannot be represented by a simple fraction without approximation.
Answer:
0.2 m³/s
Step-by-step explanation:
Applying,
Q = vA.............. Equation 1
Where Q = Flow rate of air in the pipeline, v = flow velocity of the air in the pipeline, A = cross sectional area of the pneumatic pipeline.
From the question,
Given: v = 20 m/s, A = 0.01 m²
Substitute these values into equation 1
Q = 20(0.01)
Q = 0.2 m³/s
Hence the flow rate of air in the pipeline is 0.2 m³/s
