I suppose the integral is
The integration region corresponds to a sector of a cirlce with radius 5 subtended by a central angle of π/4 rad. We can capture this region in polar coordinates by the set
Then 
, 
, and 
. So the integral becomes
119.32 = 2 x 3.14 x r
r = 19cm
area = 3.14 x 19^2
= 1133.54cm2
On the x column, you would write 1, 2, 3, 4, and so on. Then, in the y box, you plug in that number into the equation. Write your answer in the y column.
For example, if x = 1, then 1^2 + 2 - 8 = - 5.
If x = 1, y= -5
Their average speed was 52 miles per hour
