small circle is shaded and large circle has radius of 4 and small has radius of 2. what is the percent of shaded area(small circle)?

Area of larger circle = 16pi

Area of small circle = 4pi

Shaded area / Total area =  4pi / 16pi  =  1/4 = 25%

The formula for the area of a circle is π·r².

Find the ratio of the area of the small circle to the area of the large circle:

        π·2² / π·4²  =  4π / 16π  =  4/16  =  1/4  =  25%

thx i hate geometry and spaced out on lesson lol
