In the diagram below, O is the centre of a circle of radius 8 cm. Find the area of the
shaded segment XY to 2 significant figures.
[Take n = 3.14]​

4. a spring scale is constructed so that each 0.10-n increment is separated by 0.50 cm. what spring constant is necessary for the scale to be accurate? -1.0n/cm -0.10n/cm -9.8 n/cm -0.20n/cm

Which values for a and b will create infinitely many solutions for this system of equations? ax-y=8 2x+y=b

Me what is the value of x? showing work would be appreciated - ! : )
