Answer:

314 square cenntimeters

Step-by-step 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
