Answer:
942 6/7 cm²
Step-by-step explanation:
Since O = Center of bigger circle, OA = Radius of bigger circle.
∴ Area of smaller circle - Area of bigger circle = Area of shaded part.
∴ Area of smaller circle = 22/7 × 10²
= 22/7 × 100
= 2200/7
= 314 2/7 cm²
∴ Area of bigger circle = 22/7 × 20 ²
= 22/7 × 400
= 1257 1/7 cm²
∴ Area of shaded part = 1257 1/7 - 314 2/7
= 942 6/7 cm²
Answer:
the graph should be of the line y=5x
Step-by-step explanation:
the x axis should be labeled hours and the y axis should be labeled amount earned or dollars
the coordinates on the graph should be
(1,5) (2,10) (3,15) (4,20) (5,25) (6,30)
I cannot see the answer choices but I hope this information helps you answer the question
x=15-657/2=15-373/2=-5.316
x=15+657/2=15+373=20.316
