111.28 1/8=0.125 0.125*890.20=111.275 money can only have 2 decimals so round up and $111.28 is your answer.
No, it is not a function, since 6 is repeating itself and the x should never repeat if it’s a function.
Circumference is equal to diameter multiplied by pi. C=d X pi. To find the radius we need to rearrange this equation. We know what pi and the circumference are, so to find diameter we do circumference divided by pi. D=c/pi. 942/pi = 299.85. This gives us the diameter, for the radius simply divide by 2 which is 149.92 :)
2x+2=6
2x=4
x=2
Hope this helps :)
