# What Happens When the Radius of a Circle is Diminished by 10?

## What is a Circle?

A circle is a two-dimensional, closed shape that is made up of all points equidistant from a single point, called the center. This means that if you draw a line from any point on the circle to the center, the line is the same length as any other line drawn from any other point on the circle to the center. The length of this line, or distance from the center to any point on the circle, is called the radius.

## What is the Change When the Radius of a Circle is Diminished by 10?

When the radius of a circle is diminished by 10, the shape of the circle changes. The circle will become smaller, and the distance between any point on the circle and the center will decrease by 10. This means that the circumference of the circle will decrease by 20, since circumference is equal to twice the radius.

## What is the Impact of Changing the Radius?

The impact of changing the radius of a circle is significant. The area of the circle will decrease, as will the circumference. This can have an effect on any objects or shapes that are based on the circle, such as arcs or sectors. The shape of the circle may also change slightly if the radius is changed significantly.

## How Can the Change be Reversed?

If the radius of a circle is diminished by 10 and you would like to return the circle to its original size, then the radius can be increased by 10. This will return the circle to its original size, and the circumference and area will return to their original values.

## Conclusion

Changing the radius of a circle can have a significant impact on the shape and size of the circle. If the radius is diminished by 10, then the circumference and area will decrease. This change can be reversed by increasing the radius by 10. Understanding the effects of changing the radius of a circle can be useful in mathematical and engineering applications.
