Answer:
A
Step-by-step explanation:
One complete turn is 1 perimeter (aka circumference).
We have to find the length it turned, hence, its circumference.
The formula for circumference (C) of a circle is:

Where r is the radius
The radius is HALF of diameter. Given diameter is 250, the radius is:
r = 250/2 = 125 feet
Now, substituting in formula we have:

So, it turned 785.4 feet with 1 rotation.
The correct answer is A
Answer: x>38
Step-by-step explanation:
By the exterior angle theorem, x=39+38=77.
Step-by-step explanation:
- (1/7)³=1³/7³=1/343
- 2⁵=32
- 1.4²=1,4×1,4=1,96
