Answer:
area of large circle=pi×r²
area of large circle =3.14×12²
area of large circle=452.16in²
area of small circle=pi×r²
area of small circle=3.14×8²
area pf small circle=200.96in²
area of shaded circle=452.16in²- 200.96in²
area of shaded circle =251.2in²
so you multiply 12 by 8 =96
9514 1404 393
x = 25
Step-by-step explanation:
The parallel lines divide the triangle sides proportionally.
x/40 = 15/24
x = 40(15/24) . . . . multiply by 40
Answer:0.125
