Step-by-step explanation:
Not sure hope you get the answer from someone else
Step-by-step explanation:
Let's check
Circumference:-
➜2πr
➜<u>2πx</u>
New Circumference:-
➜2πr
➜2π3x
➜6πx
<u>Takin</u><u>g</u><u> </u><u>ratio</u><u>:</u><u>-</u>
➜2πx/6πx
➜1/3
➜1:3
<h3>Thus,</h3>
If we quadruple the radius Circumference will also be quadrupled.
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or 
or 
or 
Make the exponent positive
(this is as far as you can simplify)
