Answer:
The radius of the circle with the circumfrence we need to find is 15+3=18.
18*2pi=113.04
It is just 18 :)It is just 18 :)
The equation x=2t-1 represent the x-coordinate. To get the value of x, substitute t with -1.
That is: x = 2(-1) - 1
= -2-1
= -3
Likewise, the equation y=t∧-3 represent the y-coordinate. Substituting t with -1,
y = (-1)∧-3
= -1
The point that correspond to t=-1 is (-3,-1).
