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?

314.2 cm²

Step-by-step explanation:

The area of the circular cross section of the pipe is given by A = πd²/4 where d = diameter of pipe = 20 cm

So, A = πd²/4

substituting the value of d into the equation, we have

A = π(20 cm)²/4

A = π400 cm²/4

A = 100π cm²

A = 314.16 cm²

A ≅ 314.2 cm²

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
