Answer:
you plug in the 3. so you get y= 3-4 which is -1
Answer:
Yes
Step-by-step explanation:
Because 9, 12, and 15 are Pythagorean triples
Area of the circle outside
= πr2
= π(5)2
=25 π
Area of the bigger circle inside
= π x(3)2
= 9 π
Area of the smaller circle inside
= π x (2)2
= 4 π
Area of shaded region
= 25π - 9π - 4π
= 12π square unit
