Fourteen hours. The equation is 5x+20=90. Solve for X.
The circumference follows the formula
C= 2 (pi)R
R is the radius which is half the diameter when we put this into the equation we get
C = 2 (pi)(4.5)
C=28.274334
10,000-1,000=9,000 -100
8,900,i think maybe
It is equal to 26 if you didn’t understand you can ask more questions and I’ll help
I think it is 715 mph but I may have done my math wrong....
