Answer:8 π inches
Step-by-step explanation:The formula for circumference is diameter *
π
The radius of a circle is always exactly half of the circles diameter.
Therefore, the diameter will be 8 inches
Multiply the diameter, 8 by π
to determine the circumference.
Answer:
x = 20°
Step-by-step explanation:
So when I learned it we called it the exterior angle theorem not the angle sum theorem but here goes.
Since exterior angle = 110 Degrees,
--> The Inner 2 angles's sum = 110 Degrees
so, 70 + 2x = 110
=> 2x = 40
x = 20
x = 20°

<u>The equation to reflect it is:</u>
Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8
8
