A mile or two can add up to ether 5,280 or 1,760 I'm sorry I'm kinda good at math hope that helps
Answer:
radius =1.1618m
Step-by-step explanation:
circumference of circle =7.3m
2πr=7.3
r=7.3/(2π)=1.1618m
Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
