If the diameter of the smaller circle is 3.5cm, that means the radius is 1.75cm.
The area of the smaller circle is π × 1.75², which is ≈ 9.62112750162.
The diameter of the larger circle is 12.5 cm, so the radius would be half that, which is 6.25cm. The area of the larger circle would be π × 6.25², which is ≈ 122.718463031.
So now that we know the area of the larger circle and the smaller circle, we can find the area of the shaded region by subtracting the area of the smaller circle from the area of the larger circle, which is basically just 122.718463031 - 9.62112750162, which is = 113.097336. The closest answer here is 113.04, hence the answer is 113.04cm².
Answer:
The sinusoidal axis is the neutral horizontal line that lies between the crests and the troughs (or peaks and valleys if you prefer). ... Instead, it would still be the horizontal line directly between the crests and troughs which is also the average of the maximum and minimum values

2. divide the yellow marbles by the total marbles
Answer:
Area = 886cm^2
Step-by-step explanation:
34 • 16 = 544
19 • 11 = 209
25 - 11 = 14
14 • 19 = 266/2
266/2 = 133
544 + 209 + 133 = 886cm^2
