I got what you mean
The stem is equal and in the second question we do not have the radius and the answer is D but here we do not have as well and the answer is C for a similar reasoning
But in the second we need the areas and the smaller circles could be bigger or smaller inside the big one.
he instead we do have
All the arcs are half the circumference of their respective circles (since they have the diameters as their chords)
Hence is not so important my point in blue in this first question. We only care about that the arcs are half-circle, regardless their wideness
Hi
Carcass, thanks for your explanation.
My confusion here is as cirrcumference/arc/area are all depends on radius for calculation and as you rightly mentioned that radius could be different for different circles.
Therefore not sure why radius could be the same when it come to arcs and circumference? Shouldn't this vary too depends on radius value?
Or to clarify as you mentioned due to
All the arcs are half the circumference of their respective circles (since they have the diameters as their chords) therefore regardless of radius value, arc/circumference value will always be half/same accordingly? Is my understanding correct?
Could you help clarify and thanks a bunch
