Question 460915


What happens to the area of a circle when it's radius is reduced {{{2}}} times?

the area of a circle is: {{{A=r^2(pi)}}}

when it's radius is reduced 2 times,the area of a circle is: {{{A=(r/2)^2(pi)}}}

{{{A=(r^2/2^2)(pi)}}}

{{{A=(r^2/4)(pi)}}}

{{{A=(1/4)r^2(pi)}}}.....so, the area of a circle will be reduced {{{4}}} times
