Answer:
C
Step-by-step explanation:
As given Zahra has paper rectangles of different sizes.
Also, Every rectangle is 5 cm is longer than it's breadth.
So, if Length=L, then Breadth= L- 5
Or , if Breadth= B, then Length= B+5
or, if length is x and breadth is y ,then writing in terms of equation
→x=y+5
As you can see,there is not any proportional relationship between length and widths of these rectangles.
Answer: A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.

ANSWER:
r = 
Explaination:
Convert the given curve into the the polar form.
x = rcosθ
y = rsinθ
in f(x,y) = (x²-y²) - √(x²+y²) = 0
put the values of x & y in given curve equation.
We get at,
g(r,θ) = (r²cos²θ - r²sin²θ) - √(r²cos²θ + r²sin²θ) = 0
g(r,θ) = r²(cos²θ - sin²θ) - √r² = 0
We know that,
cos²θ - sin²θ = cos2θ
g(r,θ) = r²(cos2θ) - r = 0
Solve for r
Finally we get:
r =
