Al of 10. A square field has four sprinklers that spray
in the areas represented by the circles below. If
the shaded portion represents area that is not
reached by the sprinklers, find the total area that
is not reached by the sprinklers.

the square has 40*40 ft² so total is =1600ft². but you should out circle area. you know that the area of circle we use πr² and r is 10 ft... if we assume π to 3 we can find one circle has 3*10*10=300ft² and we have 4 circle totally and the answer is 1600-(4*300)=400ft²

definitely a. the others have almost all data points on one side of the line.
