Sarah only knows the diameter of a circle. what should she do to find the radius? multiply the diameter by 2. divide the diameter by 2. multiply the diameter by pi divide the diameter by pi

Therefore. The correct option is B. Divide the diameter by 2.

Step-by-step explanation:

Diameter of the circle : It is defined a line segment joining two points on the circumference of circles provided the segment passes through the center of the circle.

Radius of the circle : It is defined as a line segment joining any point on the circle to the center of the circle.

So, it can be illustrated that the radius is half of the diameter of the circle.

If we are given the diameter of the circle and we need to find the radius of the circle.

So, we will divide the given diameter of the circle by 2 to obtain the required radius of the circle.

Therefore. The correct option is B. Divide the diameter by 2.
