Answer: 135.42
Step-by-step explanation:
<span>We know that OB bisects EC where they intersect would be at point O,
so the two lengths EO and OC must be equal.
2x - 20 = 70 - x
</span>[adding x + 20 to each side]
2x - 20 + x + 20 = 70 - x + x + 20
[simplifying]
<span>3x = 90
</span>[dividing each side by 3]
<span>
x = 30 would be the answer</span>
We can get the circumference of any circle in terms of the radius with this formula. C = 2

r.
Where r is the radius of the circle.
And we will use 3.14 for

.
Plug in all the values.
C = 2 * 3.14 * 2
C = 12.56
So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.
Answer:
12 W
Step-by-step explanation:
Taking first case to establish the value of k
Substituting W with 90, I with 0.6 and R with 250 then
Now when resistance is 300 and current 0.2 then
