$10$ $10$ units.

$"circumference" = 2πr$

$10π=2πr$

$5π=πr$

$5=r$

The diameter is half of the radius, so

$5xx2=10$ units.

Diameter $= 10$

$"circumference" = π * "diameter"$

Assuming that by "pie" you mean $π$ (pi) ... your problem would be

$10 * π = π * d$

So you solve for $d$

$(10 * π)/π = (π * d)/π$

$d = 10$
