Answer:
33%
Step-by-step explanation:
The area of a circle is , where r is the radius. In this case, the area of the second largest circle is
(because the radius is 3 + 4 = 7) = 49
.
The area of the smallest circle is = 16
.
Now, the area of the shaded region is just the smallest circle's area subtracted from the second-largest circle's area:
49 - 16
= 33
To find the percentage of the logo that is shaded, we need to find the total area, which is just the area of the largest circle:
Now, we just divide 33 by 100
to get:
33/100
= 33/100 = 33%, which is our answer.
