Find the circumferences of both circles to the nearest tenth.

I need to The circumference of the blue circle and The circumference of the orange circle please and thank you!

The Orange circle is: 78.5 cm

And The Blue circle is 314.2 cm

Step-by-step explanation:

By taking the formula r^2(pi), and filling it in with the radius for the orange circle you will get 78.5. For the blue circle the radius would be the orange's radius combined with the rim given. Using the same formula you will get 314.2.  

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

351.23
