The table at right shows measurements made on a circle with a onemeter radius. Each entry in the scolumn is an arc length,and the adjacent entry in the ccolumn is the corresponding chord length, both in meters. Explain why c < s, and determine the range of values for c and for s. With s on the horizontal axis and c on the vertical axis, sketch an approximate graph of
c vs s.
s c
0.256 0.255
0.618 0.608
1.234 1.157
1.571 1.414
1.896 1.625
Then.(Continuation)Express s and c in terms of è, the central angle that intercepts s and c. Combine these equations to express c as a function of s. Graph this relationship.

drwls,
We can't draw graphs for you. You have the data to draw one yourself.
Is your symbol è supposed to be theta? Let's just call it angle A. I will assume it is in radians.
The arc length is
s = Radius*A = A
The chord length is
c = 2 R sin (A/2) = 2 sin (A/2)
c = 2 sin (s/2)
The data in the table fits that equation well.

sonia,
USE THE GIVEN SET OF POINTS TO PROVE EACH CONGRUENCE STATEMENT
E(3, 3), F(1, 3), G(2, 0), J(0, 1), K(2,1), L(1, 2);<EFG=<JKL

Anonymous,
idk this question either and the explanations above dont help
