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
I’m kinda dumb but isn’t it 0 because anything times 0 is 0
Answer:
Step-by-step explanation:

Cross multiply
5*(3x-y) = 3*(4x + 5y)
5*3x -5*y = 3*4x + 3*5y
15x - 5y = 12x + 15y
15x - 12x = 15y + 5y
3x = 20y
3x = 4y * 5
