Answer:
The radius of the circle is 10
Step-by-step explanation:
To calculate the radius of the circle we have to calculate the distance from point (0,0) to point (8, -6)
For this we have to use Pythagoras
h² = x² + y²
h² = (8 - 0)² + (-6 - 0)²
h² = (8)² + (-6)²
h² = 64 + 36
h = √100
h = 10
The radius of the circle is 10
