Answer: The answer is 314.28 cm² (approx.).
Step-by-step explanation: Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.
We need to find the area 'A' of the circular cross-section of the pipe.
Given, diameter of the circular section is

So, the radius of the circular cross-section will be

Therefore, cross-sectional area of the pipe is

Thus, the answer is 314.28 cm² (approx.).
Answer:
C
Step-by-step explanation:
given - 2x < 10 ( divide both sides by - 2 )
Remembering that the symbol is reversed when multiplying/ dividing by a negative quantity.
x > - 5 ← note reversal of symbol
solution is {x | x > - 5 } → C
