They are not equivalent.
Step-by-step explanation:
5:2 = 2,5
8:3 = 2,66...
For partial circles, first imagine that there is an entire circle. To find the area of a cicle, you use the formula A=pi*r^2 or A=3.14*r^2. Then determine how much of a circl you have so you can alter the formula. Since you have a semicircle, or half a circle, simply divide the formula in half:
A=(3.14*r^2)/2
Then plug in your radius to find the area. So for this problem you do:
A=(3.14*3^2)/2
A=28.26/2
A=14.13 is the area of the semicircle
Then since the rectangle would be 108 (18*6)
The total area is 122.13 (14.13+108)
Hope this helps!

Answer:
d ≈ 3.49 units
Step-by-step explanation:
Use the distance formula for polar coordinates to determine the distance:
(The '0' is supposed to be theta)
Plug in the values given in the question. Convert radians to degrees to simplify the process.
217π/180 = 217°
-23π/36 = -115°.
Therefore:
Begin simplifying:
Solve:
d ≈ 3.49 units
