Question

Which of the following names a radius of circle a?

Answer 1

Answer:

Therefore the third option is the name of radius i.e

$\overline{AC}$

Step-by-step explanation:

Given:

Circle A i.e A is the center of a Circle.

Radius :

The radius of a circle is the distance from the center of the circle to any point on its circumference.

A is the center of a Circle.

Therefore,

Distance From A to B i.e AB =Radius

Distance From A to C i.e AC =Radius

Distance From A to D i.e AD =Radius

Therefore the third option is the name of radius i.e

$\overline{AC}=Radius$

Also,

$\overline{BD}=Chord$

$\overline{BC}=Diameter$

$\overline{CD}=Chord$
