Answer:
Step-by-step explanation:
The formula for the circumference of a circle in terms of diameter is ...
C = πd
Then the diameter is ...
d = C/π
If we use π ≈ 22/7 and C = 66 ft, then we find the diameter to be ...
d = (66 ft)/(22/7) = (66 ft)(7/22) = 21 ft
The diameter of the pool is about 21 feet.

You're solving an equation approximating the number of farm.incidents in Wales and England between 1980-88.
F = 3500
3500 = 250x - 493000
3500 + 493000 = 250x
496500 = 250x
496500/250 = x
1986 = x
