PLEASE HELP ON MY LAST GEOMETRY PROBLEM!!

Answer:
area of circle having radius 3
is πr²=π*3²=9π square units
area of circle having radius 2
=πr²=π×2²=4π square units
again
area of big circle having radius [3+2]=5 units
=πr²=π×5²=25π square units
Now
area of shaded region=25π-4π-9π=12π or 37.7square units.
Answer:
12π units² or 37.7 units²
Step-by-step explanation:
Find the area of the 3 circles and subtract the areas of the two smallest ones.
Biggest circle area: π((3(2)+2(2))/2)² = π((6+4)/2)² = π(5²) = 25π units²
2nd Biggest circle area: π(3)² = 9π units²
Smallest circle area: π(2)² = 4π units²
Shaded area: 25π - (9π + 4π) = 25π - 13π = 12π units² or 37.7 units²
