Answer 2

Drawing Two Circles with a Common Center and Radii of 15mm and 25mm

To draw two circles with a common center at point O and radii of 15mm and 25mm, follow these steps:

1. Start by drawing a point O on a piece of paper or a drawing software. 2. Using a compass, place the needle at point O and adjust the pencil to a radius of 15mm. Draw a circle around point O. 3. Without changing the compass width, place the needle at point O again and adjust the pencil to a radius of 25mm. Draw another circle around point O.

The resulting diagram should show two circles with a common center at point O, one with a radius of 15mm and the other with a radius of 25mm.

Coloring the Region Between the Circles

To color the region between the two circles, you can use any coloring tool or software. Here's how you can do it:

1. Start by selecting a color of your choice. 2. Carefully color the region between the two circles, making sure not to color inside the circles themselves. 3. Continue coloring until the entire region between the circles is filled with the chosen color.

Naming the Colored Region

The colored region between the two circles can be referred to as a ring or an annulus. An annulus is a region between two concentric circles.
