Answer:
Circle A = 62.8 m
Circle B = 37.68 cm
Circle C = 62.8 mm
Circle D = 188.4 cm
Circle E = 21.98 dm
Step-by-step explanation:
Formulas used:
C = 2πr
C = πd
where:
C = Circumference
r = radius
d = diameter
π = pi or 3.14
Circle A
=2x3.14x10
=62.80 m
Circle B
=3.14x12

=62.80 mm
Circle D
=2x3.14x30
=188.4 cm
Circle E
=2x3.14x3.5
=21.98 dm
