An engineer is planning a new water pipe installation. The circular pipe has a diameter of d=20. What is the area of the circular cross section of this pipe? Give your answer in terms of pi.

Respuesta :

The area formula is πr². Since, we are given the diameter we need to find the radius by dividing the diameter by 2.

radius = 20/2 = 10

Area = π(10)²
Area = 100π

The area of the pipe is 100π square units in term of pi.

Hope this helps :)
