R= Diameter by 2
Therefore, r=D/2
Answer:
The answer to your question is the letter B. the diameter = 3 ft
Step-by-step explanation:
Data
Circumference = 3π feet
The Circumference is defined as the distance around the edge of a circle.
Formula
Circumference = 2πr
Process
1.- Equal the value of the circumference to the formula
2πr = 3π
2.- Solve for r
r = 3π / 2π
3.- Simplification
r = 3/2 or 1.5 ft
4.- Calculate the diameter
diameter = 2 x radius
diameter = 2(1.5)
= 3 ft
