Answer: C = 56.52 cm
Explanation:
Our task is to find the circumference of the circle, given that:
Applying the formula:
(C = circumference, d = diameter)
Plug in 18 for d, since it's the diameter; also, don't forget to use 3.14 for pi.
Answer:
C = 56.52 cm
the circumference (C) of a circle is calculated as
C = πd ( d is the diameter ) , then
C = 3.14 × 18 = 56.52 cm
