[tex]A = 100\pi cm^{2}[/tex]

Step-by-step explanation:

Given that an engineer is planning to install a new water pipe.

The diameter of the circular pipe is

d = 20 cm

Let us find the radius (r)

radius = diameter / 2

r = 20 / 2 = 10 cm

The area of circle (A) is given as:

[tex]A = \pi r^{2}[/tex]

[tex]A = \pi 10^{2}[/tex]

[tex]A = 100\pi cm^{2}[/tex]
