Step-by-step explanation:
You would need the diameter to figure this out
The radius of the circle is 1 cm, if the circle has an area of 3.14 [tex]cm^{2}[/tex].
Step-by-step explanation:
The given is,
Area of the circle is 3.14 [tex]cm^{2}[/tex],
Step:1
The formula for Area of circle,
A = π[tex]r^{2}[/tex]....................(1)
where,
π - 3.14
r - Radius of circle
Step:2
From the given,
Area, A = 3.14 [tex]cm^{2}[/tex]
Eqn (1) becomes,
3.14 = 3.14 × [tex]r^{2}[/tex] (∵ π = 3.14 )
[tex]\frac{3.14}{3.14}[/tex] = [tex]r^{2}[/tex]
[tex]r^{2}[/tex] = 1
r = [tex]\sqrt{1}[/tex]
= 1
r = 1 cm
Radius of circle, r = 1 cm
Result:
Thus the radius of the circle is 1 cm, if the area of circle is 3.14 [tex]cm^{2}[/tex].
