Terrence says pi is a rational number since it is the ratio of a circle's circumference to its diameter. Why is
kari74 [83]

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\pir and D = 2r

                C = \piD

Thus,          \pi = \frac{C}{D}

                     = \frac{22}{7}= 3.142857143...

Terrence was incorrect because Pi is an irrational number which cannot be represented by a simple fraction without approximation.

What is the flow rate of the air in the pipeline if the cross sectional area of a pneumatic pipeline is 0.01 m2 and the speed of
e-lub [12.9K]

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
