Question

The ratio of circumference of two circles is 5:3 what is the ratio of their radii

Answer 1

Answer:

the eatio of two circumference in ratio

Step-by-step explanation:

=2πr/2πR

=5/3

Answer 2

Answer:

• The ratio between radii of two circle is 5:3.

Step-by-step explanation:

Let radii of 1st circle be r₁ and radii of 2nd circle be r₂.

And circumference of 1st circle be C₁ and circumference of 2nd circle be C₂.

Given:

• The ratio of circumference of two circles is 5:3.

To Find:

• Ratio of radii of two circles.

We know that,

⇒ Circumference of circle = 2πr

Now, according to question,

$\longrightarrow \sf \dfrac{Circumference\;of\;1st\;circle\;(C_{1})}{Circumference\;of\;2nd\;circle\;(C_{2})}=\dfrac{2\pi r_{1}}{2\pi r_{2}}\\ \\ \\ \longrightarrow \sf \dfrac{5}{3}=\dfrac{r_{1}}{r_{2}}$

Hence, the ratio between radii of two circle is 5:3.

Extra Info:

What is circumference?

• The distance around a circle is called the circumference.
• Circumference = 2πr
