Question

If the circle is dilated by a scale factor of one-fourth, what will be the length of the new radius? a circle with radius of 16 centimeters. 1 cm 4 cm 20 cm 64 cm

Answer 1

4

Explanation:

A dilation of a shape's area will proportionately affect its diagonal (or in the case of a circle, its radius). Thus, we can simply multiply the scale factor (1/4) by the circle's original radius to get the length of new radius.

`16 \left((1)/(4) \right)`

`= (16)/(4)`

`= 4`
