When dividing 0.006 divided by 0.024 it becomes 0.025, i did it by calculator so dont give me credit for this lol
She is wrong because she did the square root of 25 multiplied by 2, she should have just done the square root of 50.
For the second part the square root of 50 is 7.07 which rounding would equal 7.1.
Hope this helps.(ﾉ◕ヮ◕)ﾉ*:･ﾟ✧
Both charms are "similar".
And notice one diameter is 1, the other is 4, the diameters are on a ratio of 1:4 then, and so both figures are on a ratio of 1:4.
so, if another unit, like the circumference is at 3.14 on the small one, then the large one will have a circumference 4 times that much, because the circumferences are also on a 1:4 ratio.
