We need to find the percent error of Shaun's estimate. Using the formula as follows :

Put all the values,

So, the percent error of Shaun's estimate is 38.72%.
We have the formula S= r * theta , where S is arc length , r is radius , and theta is central angle in radians
So AB= 4 * 45* π/180 = π units
54=.9x Solve for x. x=54/.9=60
