Answer:
remaining cardboard area = 122.5πr²
Step-by-step explanation:
area of original rectangle = length * width
= 18r * 8r
= 144r²
- area of semi circle:
πr²
Here we have 3 semi circles with radius 3r:
- area of 3 semi circles: 3(
* π * (3r)²)
: 3(
* π * 9r²)
: 13.5πr²
- area of one semi circle with radius 4r:
(
* π * (4r)²)
(
* π * 16r²)
8πr²
- So the area of remaining cardboard:
area of rectangle - area of 4 semi circles
144r² - 13.5πr² - 8πr²
122.5πr²

Answer:
$204.16 in interest or 644.16 total
The answer should be 32,890!
Move the decimal 4 places to the right
3.289 —> 32890
Jesse moved it 7 places to the right!
I’m not great at explaining but I hope it’ll help!

Answer:
90°
Step-by-step explanation:
Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.
_____
<em>Additional comment</em>
No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.
