Val needs to find the area enclosed by the figure. The figure
is made by attaching semicircles to each side of a
52-m-by-52-m square. Val says the area is 1,541.28 m². Find
the area enclosed by the figure. Use 3.14 for 1. What error
might Val have made?
52 m
The area enclosed by the figure is m2.
(Round to the nearest hundredth as needed.)

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
