Answer:
x < -12
Step-by-step explanation:
−21x>6
Multiply both sides by -2(−2)2−1x>(−2)6
Simplify - remember to flip the inequality symbolx<−12
Graph: ←-----------o -12
Interval Notation: (-∞, -12)
Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.
