Answer:
x = r cos theta and y = r sin theta
Step-by-step explanation:
cos theta = x / r so:-
x = r cos theta
and sin theta = y / r, so
y = r sin theta
Area of square = 10x10
= 100
area of circle = pi(r)^2
= pi (5)^2
=25pi
area of shaded = 100 -25pi
circumference of circle = 2pi (r)
= 2pi(5)
= 10pi
perimeters of shaded = 10pi + 10 + 10
= 10pi +20

Which part do you need help on?
Answer:
Both questions are true.
Step-by-step explanation:
The general mathematical equation of a line can be written as
.
If we rearrange the two equations given in the question as follows:
and 
We can see that they follow the general equation we defined earlier so we can say that they represents linear lines.
The
given in the second question also represents a similar linear line with a different slope.
So the two questions are both true.
I hope this answer helps.
