Answer:
[tex]5\:\mathrm{cm}[/tex]
Step-by-step explanation:
The circumference of a circle is given by [tex]C=2\pi r[/tex], where [tex]r[/tex] is the radius of the circle.
What we're given:
- [tex]C[/tex] of 31.4
Solving for [tex]r[/tex]:
[tex]31.4=2\cdot 3.14 \cdot r,\\r=\frac{31.4}{2\cdot 3.14}=\boxed{5}[/tex]
Answer:
Radius of circle is 5 cm.
Step-by-step explanation:
Given that
- Circumference of circle = 31.4 cm
- Using value of π = 3.14
To Find :-
Radius of circle
Formula Used
Circumference of circle = 2 × π × r
Solution :-
Using Formula
Circumference of circle = 2 × π × r
Substitute the values into the formula
31.4 cm = 2 × 3.14 × r
multiply
31.4 cm = 6.28 × r
Divide , we get
31.4 cm /6.28 = r
5 cm = r
Hence, Radius of circle is 5 cm.
