The circumference of a circular flower bed is 17.27 meters. What is its diameter?
Tell me, what information have you discovered?
How to find the diameter of a flower bed if its circumference is known?
method one:
Because C = πd
So diameter=17.27÷3.14 =5.5 (meter)
Answer: The diameter of the flower bed is 5.5 meters.
Method Two:
Solution: Suppose the diameter of the flower bed is x meters.
3.14x=17.27
x=17.27÷3.14
x=5.5
Answer: The diameter of the flower bed is 5.5 meters.
