Question

find the radio of two circle is the ratio of 2 upon 5

Answer 1

Answer : 2:5

Solution :
________

Given that : the ratio of radius of two Circle = 2:5

Let, the Radius of first circle = 2x and

The radius of second circle = 5x

Then, the ratio of their circumference :

${2\pi2x} \div 2\pi5x \\ \\ = > \frac{2\pi2x}{2\pi5x} \\ \\ = > \frac{2(2\pi \times x)}{5(2\pi \times x)}$

So, the ratio of their circumference will also be 2:5
