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.).
Hello there!
Now, the formula to find the circumference of a circle is C = 2
r. Now, since the circumference is 18
, all we have to do is to divide 18 by 2 to find the <em>radius!</em>
The radius of the circle is 9 cm, since 18/2 = 9. However, this is the radius. We need the diameter.
Multiply 9 by 2 to find the diameter. 9 · 2 = 18. So
the answer is B. 18 centimeters.
Hope this helped!
