Answer:
464 π in²
Step-by-step explanation:
The smallest circle has a radius of 8 in.
The middle circle has a radius of 8 + 4 = 12 in.
The largest circle has a radius of 12 + 4 = 16 in.
So the sum of the areas is:
π (8 in)² + π (12 in)² + π (16 in)²
= 64π in² + 144π in² + 256π in²
= 464π in²
B. 90
Because, a circle is 360 degrees total. Angle FG is 130 degrees. Angle GD is 90 degrees. It's remaining 2 so.... 130+90=220 But every circle is 360 degrees so... 360-220=140. And ED looks similar to GD which is 90 degrees
