Formula for the Circumference of a Circle = pi x diameter
---The diameter is the same thing as 2 x radius
Circumference = 8
pi = 3.14
Diameter = d
---First, plug in what we know
8 = 3.14 x d
---Divide by 3.14 to get d by itself
d = 8 / 3.14 = 2.54777
---Round to the nearest tenth
d = 2.5 cm
Hope this helps!
Answer:
d=2.5
Solution:
- Circumference:
- C=πd
- 8=πd
- Since we can't simplify this equation yet, we can divide both sides by 3.14 (which is the same as pi) in order to isolate d:
- 8÷3.14=d
- d=2.5
Hope it helps.
