Question

Find the diameter of a circle whose circumference is 18.85 m.

A. 3.46 m
B. 2.45 m
C. 6 m
D. 12 m

Answer 1

C

Explanation:

the formula for calculating the circumference ( C) of a circle is

C = πd ← d is the diameter

divide both sides by π to isolate d

d =
`(C)/(\pi )` =
`(18.85)/(\pi )` = 6 m → C
