An engineer is planning a new water pipe installation. the circular pipe has a diameter of d=20\text{ cm}d=20 cmd, equals, 20, start text, space, c, m, end text.
what is the area aaa of the circular cross section of this pipe?
give your answer in terms of pi.

Area of circular pipe in terms of pi is found as square centimeter

Solution:

Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm

We have to find the area 'A' of the circular cross-section of the pipe.

Given, diameter of the circular section is:

diameter = 20 cm

Let us find the radius

Thus radius = r = 10 cm

The area 'A' of the circular cross-section of the pipe measn we can use the area of circle formula

The area of circle is given as:

Where "r' is the radius of circle

We have to find area in terms of pi

Thus area of circular pipe in terms of pi is found as square centimeter
