The equation of a line that passes thruogh the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so
passing through (a,b) and having slope of b is
y-b=b(x-a)
Answer:
Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed. I don't know exactly how to interpret the rest of the question. If r is a positive rational number and p is some positive real number, then sqrt(r^2 p) / sqrt(p) is always rational, being equal r. Possibly your question refers to situtions in which sqrt(c) is not uniquely determined, as for c negative real number or complex non-real number. In those situations a discussion is necessary. Also, in general expressions the discussion is necesary, because the denominator must be different from 0, and so on.

Answer:
The area of the cone is "1,695.6 cm³".
Step-by-step explanation:
The given values are:
Diameter of cone,
d = 18 cm
then,
Radius,
r = ![\frac{d}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7B2%7D)
= ![\frac{18}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B2%7D)
= ![9 \ cm](https://tex.z-dn.net/?f=9%20%5C%20cm)
Height,
h = 20 cm
As we know,
⇒ Area of a cone = ![\frac{1}{3} \pi r^2 h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20r%5E2%20h)
On substituting the given values in the above formula, we get
⇒ = ![\frac{1}{3}\times 3.14\times (9)^2\times 20](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Ctimes%203.14%5Ctimes%20%289%29%5E2%5Ctimes%2020)
⇒ = ![\frac{1}{3}\times 3.14\times 81\times 20](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Ctimes%203.14%5Ctimes%2081%5Ctimes%2020)
⇒ = ![3.14\times 27\times 20](https://tex.z-dn.net/?f=3.14%5Ctimes%2027%5Ctimes%2020)
⇒ = ![1,695.6 \ cm^3](https://tex.z-dn.net/?f=1%2C695.6%20%5C%20cm%5E3)
