How many centimeters of lace does she need if the radius is 12 cm?
B. What are the given facts?
Radius =12 cm
C. What Formula Is Needed?
(Formula And Operation is The same).
Circumference= 2πr
D. Solve And give the Answer?
C= 2πr ; π=3.14
C=2 x 3.14 x 12
C= 75.36 cm
They need 75.36cm lace.

A. what is asked?
B. What are the given Facts?
diameter= 48cm
C. What Formula is needed
(Formula and Operation is The same.)
C=πD
D. Solve and give the answer.
C= πD
C = 3.14 x 48
C = 150.72 cm
150.72 cm or 1.5072 m
