Question

• The radii of two circle are in the ratio 2 : 3 what is the ratio of their circumference?

Answer

• Ratio of circumference = 2:3

Given

• Radius of two circles are in ratio 2:3

To Calculate

• Ratio of circumference __?

Step by step explanation

Radius of two circles are in ratio 2:3(Given)

Let the radius of two circles be 2x and 3x

${\boxed{\red{\tt{Circumference\:of \: Circle = 2πr}}}}$

Circumference of First Circle = 2×π×2x

➩ 4x×π

Circumference of Second Circle = 2×π × 3x

➩ 6x × π

Ratio of circumference of Two circles

$= \frac{4x \times \pi}{6x \times \pi}$

➩ 4/6

➩ 2/3

➩ 2:3

$\bf\underline{\underline{\blue{HENCE:-}}}$

• Ratio of circumference = 2:3
