Question

Name a Radius

A. AP
B. AB
C. DE
D. All of the above
please help I'll really appreciate it ​

Answer 1

`\large{ \tt{❃ \: EXPLANATION}} :`

• Radius is the line segment that joins the centre of a circle and any point on its circumference. In the figure , AP is the radius. The plural form of radius of radii. All the radii of a circle are equal i.e AP , PB & PC are radii and they're equal.

`\large{ \tt{❁ \: LET'S \: CHECK \: THE \: OPTIONS: }}`

• 
  `\large{ \tt{ \overline{AP}}}` - Yes!
  `\tt{ \overline{AP }}` is a radius since it is the line segment which joins the centre of a circle and any point on the circumference.

• 
  `\large{ \tt{ \overline{ AB}}}` - No! It's a diameter since it is the line segment that passes through the centre of a circle and joins any two points on its circumference. Remember: The length of a diameter is two times radius i.e if the length of radius [ AP ] is 5 then the length of Diameter [ AB ] will be 5 × 2 = 10.

• 
  `\large{ \tt{ \overline{ DE}}}` - No! It's a chord since it is the line segment which joins any two points on the circumference of a circle.

Answer 2

AP is the radius since it's a straight line extending from the center. CP and BP are radiuses as well
