Question

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?

Answer 1

314 square cenntimeters

Explanation:

Area of the circular cross-section of the pipe = πd²/4

Given that;

d = 20cm

Area = π(20)²/4

Area = 400π/4

Area = 100π

Area = 100(3.14)

Area = 314cm²

Hence the area of the circular cross-section of this pipe is 314 square cenntimeters
