Progress overview
The
circumference
of a
circle
can be found by multiplying the diameter by π.
C= π d We know that this circle has a
diameter
of 15 centimeters, so we can substitute 15 for d in the formula.
C=Ď€ d
Substitute
d= 15
C=Ď€* 15
Multiply
Multiply
C=15Ď€
The circumference is 15Ď€ centimeters.
