Question

9. If the radius of a circle is increased by
three times, then by how many times
does the diameter increase?​

Answer 1

Answer:

6 cm

Step-by-step explanation:

6 cm bro

Answer 2

Answer:

3 times

Step-by-step explanation:

Here's the proof to it

let radius be x then diameter will be 2x

on increasing radius by 3 time it becomes 3x

then diameter will be 3x × 2 = 6x

on increasing actual diameter that is 2x by 3 times we get 6x.

Therefore we conclude that if radius of a circle is increased by 3 times its diameter also increases by 3 times.
