Answer:
radius = 5.75 units
circumference = 36.11 units
Area = 103.81625 square units
Step-by-step explanation:
Radius = 11.5 / 2 = 5.75
Circumference = 11.5 x 3.14 = 36.11
Area = 5.75 x 5.75 x 3.14 =
33.0625 x 3.14 =
103.81625 units square
This is all if pi = 3.14
Hope that helps!

Answer:
Hans has done a mistake in the second step.
The correct answer is:
5x^2+13x-6=0
5x^2+15x-2x-6x=0 - 5. -6=-30 -30=15. -2
5x(1+3x)-2x(1+3x)=0
(5x-2x)(1+3x)=0
5-2x=0 1+3x=0
x=5/2 x=-1/3
