Answer:
B
Step-by-step explanation:
the hypotenuse of the right triangle is the diameter d of the circle
Using Pythagoras' identity in the right triangle
d² = 6² + 8² = 36 + 64 = 100 ( take square root of both sides )
d = [tex]\sqrt{100}[/tex] = 10
the circumference (C) of a circle is calculated as
C = πd = π × 10 = 10π
