Answer:
X = 9
92 + 34 + 54 = 180 degrees
Step-by-step explanation:
180-14x + 92 + 3x + 7 = 180
-11x + 99 = 180 - 180
99 = 11x
X = 9
Answer:
The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =
⇒ answer C
Step-by-step explanation:
In any circle there is a constant ratio between the circumference of the circle and its diameter
This constant ratio is called π
∵ The formula of the circumference of a circle is C = π d,
where d is the diameter of the circle
- Divide both sides by d
∴
= π
- Switch the two sides
∴ π =
∵ The diameter of the circle is 5 centimeters
∴ π = 
The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =
