a. r = 7 cm; d = ░
b. d = 5 in; r = ░
c. r = 4.2 ft; d = ░
What is the exact measure of the circumference?
d ≈ 30.6 mm
r ≈ 3.18 ft
Simplify (Round to the nearest tenth):
a fraction of the circumference of a circle
the ratio of the length of an arc to the circumference is equal to the ratio of the measure of the arc to 360º
