Answer 1

The correct answer is 1.2 cm

Answer 2

its wrong

Answer 3

Apologies for the incorrect response. The correct answer is 1.2 cm.

Answer 4

There is no 1.2

Answer 5

Apologies once again. Let's try solving the problem correctly.

If we use a scale factor of 15 to dilate the circle with a radius of 18 cm, we multiply the radius by the scale factor to find the radius of the original circle.

Original radius = Scale factor * Radius of dilated circle
Original radius = 15 * 18 cm

Therefore, the radius of the original circle before dilation would be 270 cm.

Answer 6

still wrong

Answer 7

I apologize for the confusion. Let's solve the problem again.

If we use a scale factor of 15 to create a circle with radius 18 cm, the radius of the original circle before dilation can be found by dividing the radius of the dilated circle by the scale factor.

Original radius = Radius of dilated circle / Scale factor
Original radius = 18 cm / 15

Therefore, the radius of the original circle before dilation would be 1.2 cm.

Answer 8

What scale factor will produce a dilated image that is smaller than the original image?
a negative scale factor

a scale factor equal to 1

a scale factor less than 1

a scale factor greater than 1

Answer 9

A scale factor less than 1 will produce a dilated image that is smaller than the original image.
