Respuesta :

Answer:

4%

Step-by-step explanation:

the area of the little circle is 25π and the area of the big circle is 625π

divide the inner circle by the outer circle   25/624 = .04 = 4%

Answer:

The center of the target takes up 4% of the whole target.

Step-by-step explanation:

Use the formula A = πr²

to find the area of the center of the target and the area of the whole target.

π(2.5)²

π(12.5)²      =   6.25/  156.25  =   1 /25

 Convert the fraction to a percent.

1 /25      = 0.04 Convert  

1 /25  into a decimal = 4% Convert 0.04 to a percent.
