This formula only applies if the track is circular. If it is, then we write the equation:
2*r*pi=400
Dividing by 2pi, we see that:
r=200/pi
This is approximately 63.66.
It will be clearly B.38mm3
I think its B because, the formation would be (x,y) so that means (5,-3)
The answer is: [D]: " 2.6 " .
_____________________________________________________
Given: a = - 2.6 ; What is the value of "-a "?
_____________________________________________________
So, what is the value of " - (-2.6)" ?
_____________________________________________________
The opposite of a negative is a positive;
so, " - (-2.6) = 2.6 " ; which is: "Answer choice: [D] " .
