Answer:
D or 4
Step-by-step explanation:
3x3.1415 is ~9.42
sq. rt. of 10 is ~3.16 so order them.
3.16 3.25 9.42 or 10, 3.25, 3pi
The answer of the larger circle = 254.34
Formula = radius*radius*π
The answer of the smaller circle = 113.04
254.34 - 113.04 = 141.3
Hope this helped☺☺
The complete question in the attached figure
we know that
[arcs rc +arc cs arc sm]---------------> they take up half a circle-------->180°
<span> they are all congruent
so
divide 180 by 3 ----------------> 180/3=60</span>°
Find the length of arc rc=60°<span>
if 360</span>°----------------> (2*pi*7) length of circumference
60° -------------------> X
<span>X=60*2*pi*7/360------------> 7.327 units
the answer is
</span>
the length of arc rc= <span>
7.33 units</span>
