Question

the diameter of a circle is ______ the radius​

Answer 1

Answer:

double

Step-by-step explanation:

2*radius = diamneter

Answer 2

The diameter of a circle is twice the radius.

What is the radius of a circle?

• The radius of a circle is any chord drawn from the center of the circle to any other point on the circle.

What is the diameter of a circle?

• The diameter of a circle is any chord drawn from one point in the circle to another point, given that it passes through the center.

• Let us assume a circle with center O.
• A and B are two points on the opposite ends of the circle.
• If we draw a line from O to A and from O to B we see that both OA and OB are radii of the circle.
• AB is the diameter of the circle.
• All radii are equal for a circle, so:

                             OA=OB

                 and OA + OB = AB

                 ⇒ 2(OA) = AB

                ⇒ 2 × Radius = Diameter

Thus from the definition of diameter and radius, we can conclude that the Diameter of a circle is twice the Radius.
