A circle has a diameter of 8 m. what is the circumference? use 3.14 for pie
2 answers:
Radius = half of diameter
radius = 4m
circumference of a circle = 2πr
circumference = 2(3.14)(4)
circumference = 25.12
Answer: 25.12 m
Step-by-Step Explanation:
d = 8 m
r = 8/2 = 4 m
π = 3.14
Circumference = 2πr
Therefore,
= 2πr
= 2 * π * r
= 2 * 3.14 * 4
= 6.28 * 4
= 25.12 m
Circumference = 25.12 m
