X(u, v) = (2(v - c) / (d - c) + 1)cos(pi * (u - a) / (2b - 2a))
y(u, v) = (2(v - c) / (d - c) + 1)sin(pi * (u - a) / (2b - 2a))
As
v ranges from c to d, 2(v - c) / (d - c) + 1 will range from 1 to 3,
which is the perfect range for the radius. As u ranges from a to b, pi *
(u - a) / (2b - 2a) will range from 0 to pi/2, which is the perfect
range for the angle. So, this maps the rectangle to R.
Answer:
A. The balloon is at its initial height
B. The boxer is 0 pounds from her starter weight
C. The company's size is smaller
Step-by-step explanation:
For A, -30+30 is equal to 0 so its gonna be the same height it was before.
For B, Gaining 7 pounds and losing 7 pounds means you are neither bitter or smaller. (-7+7=0)
For C, Losing 15 employees and gaining none means that there are less than there were previous meaning the company is now smaller.
Hope this helps.

Answer:
The value of radius is 34.395..
Step-by-step explanation:
The formula for finding the circumference of the circle is:
C=2πr.
Here we have given the values:
circumference = 216 units
π = 3.14.
r = ?
Substitute the values in the formula:
216 = 2(3.14)r
216=6.28r
Now divide both sides by 6.28.
We get,
216/6.28 = 6.28r/6.28
34.395=r
Thus the value of radius is 34.395...
