SOLVING

$\Large\maltese\underline{\textsf{A. What is Asked}}$

If a Circle has a circumference of
$\bf{20\pi}$ , what is its diameter?

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

The equation used, here is
$\bf{C=\pi d}$ .

Let's start by putting in what C equals.

$\bf{20\pi =\pi d$ | divide both sides by pi

$\bf{20=d}$

$\cline{1-2}$

$\bf{Result:}$

$\bf{=d=20,\;the\;fourth\;option}$

Since you are given the circumference and want to find the diameter, isolate d in the formula for circumference: C = πd.

C = πd

Divide both sides by π.

C/π = d

d = C/π

Plug in the given value for C and solve for d.

d = C/π

d = 20π/π

The pis cancel out, leaving 20 on the left side of the equation.

d = 20
