Angle c is inscribed in circle O. AB is a diameter of circle O. what is the radius of circle.​
Llana [10]

Answer:

The value of radius is 7.5 units

Step-by-step explanation:

Given that a line that pass through the origin and form a triangle is a right-angle triangle. So in order to find the diameter/hypotenuse, you have to use Pythogaras Theorem :

{c}^{2}  =  {a}^{2}  +  {b}^{2}

Let a = 12 units,

Let b = 9 units,

Let c = hypo.,

{hypo.}^{2}  =  {12}^{2}  +  {9}^{2}

{hypo.}^{2}  = 225

hypo. =  \sqrt{225}

hypo. = 15 \:  \: units

We have found out that the hypotenuse of the triangle is the diameter of circle. So in order to find radius, you have to divide it by 2 :

radius = diameter \div 2

radius = 15 \div 2

radius = 7.5 \:  \: units
