Question

solve the formula $c = pi d$ for $d$.
a. $d = \frac{c}{\pi}$
b. $d = \pi c$
c. $d = c - \pi$
d. $d = \frac{\pi}{c}$

Explanation:

Step1: Isolate \( d \)

We have the formula \( C = \pi d \). To solve for \( d \), we need to isolate \( d \) on one side of the equation. We can do this by dividing both sides of the equation by \( \pi \).
\[
\frac{C}{\pi} = \frac{\pi d}{\pi}
\]

Step2: Simplify

Simplifying the right - hand side, \( \frac{\pi d}{\pi}=d \) (since \( \pi
eq0 \), we can cancel out \( \pi \) in the numerator and the denominator). So we get \( d=\frac{C}{\pi} \).

Answer:

A. \( d = \frac{C}{\pi} \)
