Answer:
x is = 11.7 μ=7
z11.7 ≈ 1.3
next two is A and B
Step-by-step explanation:
These are correct 100%
Circumference is 2πr or πd.
So for part 1 the diameter = 9in.
Plug in 9 into the πd formula.
π*9 = 9π in. ≈ 9*(22/7) ≈ 28.29in
For part 2 (from what I can see) they want you to find the same circumference in centimeters(cm) and use 22/7 for π so first convert the radius to cm.
9 in = 9*2.54 = 22.86cm
Next plug in the values into the Circumference formula: π*d
(22/7)*(22.86) ≈ 71.85cm
Hope this helps!
