You can flip a coin, heads can be true and tales can be false.
To convert from rectangular coordinate (x, y) to polar coordinate (r, θ).
r is given by the square root of the sum of the squares of the rectangular coordinate.

and θ is given by the arctan of the ratio of y to x.

Example:
To convert rectangular coordinate (3, 4) to polar coordinate

Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
I'm not sure but I think it's 15
Answer: GCF(8,10) = 2
Step-by-step explanation:
Factors of 8
1, 2, 4
Factors of 10
1, 2, 5
The area of the circle would be pi r^2 and the area of the square will be side^2. r is 12 and the side is 12rad(2). the circle would have an area of 144 pi and the square an area of 288. so 452.39-288 =164.4
