Yes the person is right I was trying to type it but they beat me to it
Answer:
The answer is D. 393ft
Step-by-step explanation:
So if you do 62.5•2=125
Then you do 125•3.14=392.5
After that then you round 392.5 and you get 393
theres your answer.
Answer:
line a and b are parallel, there is no perpendicular lines
Step-by-step explanation:
Looking at the slope of each line, you can identify whether the lines are parallel, perpendicularlar, or neither.
When the slopes are the same, they are parallel.
When the slopes have opposite sign and numerator and denominator flipped, they are perpendicular. Ex.
and
are perpendicular slopes.
Finding slope is using the formula: 
Line a has slope
= 
Line b also has slope 
Line c has slope 2
Since slope of line a and b are same, they are parallel.
Line c is not perpendicular to line a and b because the slope should have opposite sign and numerator and denominator flipped, which is 4 not 2.
