#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#
