Answer:
true
Step-by-step explanation:
The answer i believe is C
The ratio of circumference to diameter is independent of the radius.
Defining C=circumference, r=radius, D=diameter = 2r
Circumference = C = 2 π r = π D
=>
ratio of circumference / diameter
= C/D = π
Answer:
tan 21 = 17 000 / d
d = 17000/ tan21 = 44286.5 ft
