Answer 2

Option-A is correct that is d = 2r because the diameter is the two times of radius in the circle.

Given that,

If r and d are the radius and diameter of the circle.

We have to choose the correct answer.

We know that,

What is circle?

The circumference is the term for the circle's perimeter.

The radius, which is represented by the letters "R" or "r," is the line that extends from the circle's "O" center to its circumference.

The diameter is the line that runs through the center of the circle and touches the two points on its circumference; it is represented by the letter "D" or "d."

Arc is the region of a circle's circumference where its largest arc is referred to as the major arc and its smallest as the minor arc.

A sector is a piece of a circle that is enclosed by two radii and the circle's included arc.

The chord is the straight line that connects any two points on a circle's circumference.

Tangent

The tangent is a line that meets a circle's circumference at a single point.

Secant

The secant is a line that divides a circle into two different points.

Therefore, Option-A is correct that is d = 2r because the diameter is the two times of radius in the circle.
