Question

A circular swimming pool has a diameter of 12 m.

What is the approximate circumference of the swimming pool?
Use pi star times = 3.14.
Express your final answer to the nearest hundredth.

Answer 1

circumference of a circle = 2πr
so circumference = 2xπx(12/2)
=12*3.14
= 37.68 to the nearest hundreth

Answer 2

circumfereince=pid
pi=3.14 for now
d=diameter
d=12
C=12*3.14
C=37.68 m

answer is 37.68m
if you wanted more acurite, then find to the thoustadth and round (you would ge 37.692 )
