1.
\(T = (d)/(s)\): The unknown variable
\(s\) is \(7\).

2.
\(P = (W)/(t)\): The unknown variable
\(t\) is \((7)/(32)\).

3.
\(V = (1)/(3) \pi r^2 h\): The unknown variable
\(r\) is \(\sqrt{(40 * 3)/(8 * \pi)}\).

4.
\(I = prt\): The unknown variable
\(t\) is \((23)/(230 * 0.02)\).

Let's substitute the given values into each formula and solve for the unknown variable.

1. Formula:
\(T = (d)/(s)\)

- Given values:
\(T = 9\), \(d = 63\)

- Substitute and solve:
\(9 = (63)/(s)\)

- Solve for
\(s\): \(s = (63)/(9) = 7\)

So, the unknown variable
\(s\) is \(7\).

2. Formula:
\(P = (W)/(t)\)

- Given values:
\(P = 32\), \(W = 7\)

- Substitute and solve:
\(32 = (7)/(t)\)

- Solve for
\(t\): \(t = (7)/(32)\)

So, the unknown variable
\(t\) is \((7)/(32)\).

3. Formula:
\(V = (1)/(3) \pi r^2 h\)

- Given values:
\(V = 40\), \(h = 8\)

- Substitute and solve:
\(40 = (1)/(3) \pi r^2 * 8\)

- Solve for
\(r^2\): \(r^2 = (40 * 3)/(8 * \pi)\)

- Solve for
\(r\): \(r = \sqrt{(40 * 3)/(8 * \pi)}\)

So, the unknown variable
\(r\) is \(\sqrt{(40 * 3)/(8 * \pi)}\).

4. Formula:
\(I = prt\)

- Given values:
\(I = 23\), \(p = 230\), \(r = 0.02\)

- Substitute and solve:
\(23 = 230 * 0.02 * t\)

- Solve for
\(t\): \(t = (23)/(230 * 0.02)\)

So, the unknown variable
\(t\) is \((23)/(230 * 0.02)\).
