C=2*π*r use the formula you derived to solve for the circumference of the high roller, the tallest ferris wheel in the united states, if the ferris wheel has a radius of 260 feet. show all work in the space below.

R in the formula stands for "radius." Your problem statement tells you the radius is 260 ft, so put that number in the formula and do the arithmetic. Most scientific calculators have a key for "π". If yours doesn't, you can use the ratio 355/113 as a good approximation.

C = 2*π*(260 ft)
C = 520π ft . . . . . . multiply numerical values to express result using π
C ≈ 1633 ft . . . . . .. compute numerical value of circumference

Ithink if im not mistaking b is -3 but im not a 100% sude
