What happens to the area of a circle when it's radius is reduced 2 times?
the area of a circle is: A=r%5E2%28pi%29
when it's radius is reduced 2 times,the area of a circle is: A=%28r%2F2%29%5E2%28pi%29
A=%28r%5E2%2F2%5E2%29%28pi%29
A=%28r%5E2%2F4%29%28pi%29
A=%281%2F4%29r%5E2%28pi%29.....so, the area of a circle will be reduced 4 times
