Area of a sector (A) with a central angle (€) of 5π/7 radians and a diameter of 5.6 in.
Use 3.14 for π, radius (r) = d/2 = 5.6/2 = 2.8in.
A = (€ radians/2π radians)•π r^2
A = (5π7 radians/2π radians)•π (2.8in)^2
A = 5/14•π 7.84 in^2
A = 0.357•3.14•7.84 in^2
A = 8.79 in^2

Answer:
30%
Step-by-step explanation:
Method 1-
Divide 9 by 9/30. You get 30. This is the percent that you need!
Method 2-
You can also simplify 9/30 down to 3/10. You just multiply this by 10 on both sides. This makes 30/100, or 30%
