To find the radius of the original circle, you need to reverse the dilation process.
The skill factor of 3/4 means that the new circle is 3/4 times the size of the original circle. Therefore, the radius of the new circle is 3/4 times the radius of the original circle.
If the radius of the new circle is 9 units, then the radius of the original circle can be found by dividing 9 by 3/4:
Radius of original circle = 9 / (3/4) = 9 * (4/3) = 36 / 3 = 12 units
Therefore, the radius of the original circle is 12 units.
You use skill factor of 3/4 to create a dilated circle with a radius of nine what is the radius of the original circle?
