Answer:
z=-1
Step-by-step explanation:
First combine the like terms: -4z-11z+2z-(-6z)=-4z-11z+2z+6z=-15z+8z=-7z
Then solve after combining like terms:
Arc length: s = radius (central angle)
Here, 18 cm = (radius)(7pi/8)
Solving for the radius:
18 cm (18 cm)(8)
radius = --------------- = ------------------ = ? Please calculate this.
(7pi/8) 7pi
Answer:
You are only given a Side, an Angle, and then a side. So that is what I would choose. It can't be AA because you weren't given two angles. It can't be SSS because you weren't given 3 sides.
Step-by-step explanation:
Answer:
A ≈ 12.57
Step-by-step explanation:
You have to take the formula: A = πr^2
1) Plug in what you know: A = π•2^2
2) π = 3.14 and 2^2 = 4
3) Multiply to get: 12.56637
4) Round
A ≈ 12.57
