Question

The blue segment below is a radius of o. what is the length of the diameter of the circle

Answer 1

Answer:

The length of the diameter of circle  is 18.6 units

Step-by-step explanation:

Given : Radius of circle(r) = 9.3 units

To Find : The diameter of a given circle

Solution :

Definition of Diameter : It is a straight line segment  whose endpoints lie on the circle that passes through the center of the circle . It is the longest chord . It is the twice of the radius .

Using the property ( Diameter is twice of radius )

Since radius of circle (r) is 9.3 units

Thus diameter :

$2*r$

⇒$2*9.3$

⇒$18.6$

Hence the length of the diameter  is 18.6 units .

Answer 2

The answer is D. 18.6 units.
The radius is half the diameter so to find the diameter you would simply multiply the radius by 2.
Hence: 9.3*2=18.6
