Answer:
8 cm
Step-by-step explanation:
the 3 cm line from the chord to the center of a circle is a leg of a right triangle which perpendicularly bisects the chord into two equal halves
draw the hypotenuse of the right triangle from the center of the circle to the endpoint of the chord. This is a radius measuring 5 cm.
find the missing leg of the right triangle
a^2= c^2- b^2
a^2= 25-9
a^2=16
a=4
this is only the measurement of half the chord. To find the full length of the chord multiply by two
4*2=8 cm

Answer:
I got 40210.1
Step-by-step explanation:
4,567.89+7,894.56=12462.45
12462.45+1,232.45=13694.9
13694.9+1,474.10=15169
15169+2,585.20=17754.2
17754.2+3696.36=21450.56
21450.56+3,214.56=24665.12
24665.12+6,545.65=31210.77
31210.77+7,898.78=39109.55
39109.55+1.100.55=40210.1
