Answer 1

$\huge{\mathfrak\red{Solution}}$

The radii of two circles are in

the ratio 2:3. What is the ratio

of their circumference?

Let us assume the radius of two circles be 2x and 3x accordingly.

Given,

Circumference of a circle= 2πr

Circumference of first circle= 2×π×3x

6x×π

Ratio of the circumference of given circles,

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

$\huge \frac{4}{6} = \frac{2}{3}$

Therefore the ratio of the given circumference is 2:3.

Hence, Found
