Answer: the area of the star is 1.94in squared

Step-by-step explanation: One part of the quarter circle has a radius of 1.5 inches because 3 inches is the height of the square.

So the diameter of 4 of the quarters would be 3 inches because 4 quarters of a circle would make a full circle with a diameter of 3. The area of a full circle with the diameter of 3 is 7.06. The area of the square is 9 because 3x3 is 9. 9 minus 7.06 leaves 1.94 in area left in the square. :) 1.94 is rounded also

Step-by-step explanation:

PRIMERO ENCONTRAMOS EL ÁREA DE UNO DE LOS

SEGMENTOS DE C´RCLO SUPONIENDO QUE EL RADIO

ES IGOAL A LA MITAD DEL LADO DEL CUADRO

A = [tex](1.5 in)^{2}[/tex] - 3.14[tex]/1.5 in)^{2}[/tex]/4 = [tex]0.49 in^{2}[/tex]

LUEGO SE MULTIPLICA POR 4

[tex]1.96 m^{2}[/tex]

SE ENCUENTRA EL ÁREA DEL CUADRADO

A = [tex]3 in ^{2}[/tex] = [tex]9 in^{2}[/tex]

FINÁLMENTE SE ENCUENTRA EL ÁREA DE LA ESTRELLA

A = [tex]9 in^{2}[/tex] - [tex]1.96 in^{2}[/tex] = [tex]7.04 in^{2}[/tex]
