Answer:
r = √98
Step-by-step explanation:
angle A and the diameter form an isosceles right triangle, with OA as the hypotenuse and r as the other sides. You can then make and solve an equation from the Pythagorean Theorem:
r^2 + r^2 = 14^2
2r^2 = 14^2
2r^2 = 196
r^2 = 98
r = √98
Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The angle A is 90 degree.
The side OA is 14.
There will be a right triangle formed.
So, Using Pythagorean theorem,
[tex]r^2+r^2=14^2[/tex]
[tex]2r^2=196[/tex]
Dividing 2 in both sides
[tex]r^2=\frac{196}{2}=98[/tex]
[tex]r=\sqrt{98}[/tex]
[tex]r=7\sqrt{2}[/tex]
So,the answer is [tex]7\sqrt{2}[/tex] : Answer
Hope it will help :)
