A chord is 6.0 cm from the centre of a circle of radius 10 cm. How long is the chord to the nearest tent of a centimeter???

Did you make a diagram?
draw a line from the centre to the end of the chord.
Looks like we have a right angled triangle with hypotenuse 10, one side 6, the other x, where x is 1/2 the chord
x^2 + 36 = 100
x = 8
sos the chord is 16
