The circumference follows the formula
C= 2 (pi)R
R is the radius which is half the diameter when we put this into the equation we get
C = 2 (pi)(4.5)
C=28.274334
Answer:
The answer to your question is:
a) 8.2 mi
b) 4.1 mi
c) 4.7 mi
Step-by-step explanation:
For 30°
sin Ф = opposite leg / hypotenuse
hypotenuse = opposite leg / sin 30
hypotenuse = 4.1 / sin 30 = 4.1 / 0.5
hypotenuse = 8.2 mi
For 90°
d must be 4.1 mi because is over the observer at this angle
For 120°
distance = opposite leg / sin 60
distance = 4.1 / √3/2
= 4.71 mi
I hope it helps you!
Answer:
Step-by-step explanation:e equation has a leading coefficient of 1 or if the equation is a difference of squares. The zero-factor property is then used to find solutions. ... Another method for solving quadratics is the square root property. The variable is squared.
