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

Find the Area &amp; Circumference of a circular pizza with a diameter of 22.0cm.
nirvana33 [79]

Answer:

  • Circumference = 69.14cm
  • Area = 380.29cm²

Step-by-step explanation:

Circumference.

Circumference of a circle is calculated by the formula:

= Pie * diameter

= π * diameter

= 22/7 * 22

= 69.14 cm

Area

Area of circle:

= Pie * radius ²

Radius = diameter/2

= 22/2

= 11 cm

Area = 22/7 * 11²

= 22/7 * 121

= 380.29 cm²

Pls help me to answer this​
Flauer [41]

Answers:

T-shirt = $25

Shorts = $15

Books = $50

Shoes = $30

Cell phones = $750

===============================================

Explanation:

Taking 10% of a number is simply moving the decimal point over one spot to the left.

For example, the selling price of a t-shirt is $250.00 and taking 10% of this gets us to $25.00

As another example, 10% of 150.0 is 15.0

If a whole number ends with a 0, then taking 10% of the number means we chop that zero off.
