Step-by-step explanation:
Given:
F = n/4 + 37
Where,
F = temperature in degrees Fahrenheit
n = number of times per minute crickets chirps
Find F when n = 80
F = n/4 + 37
F = 80/4 + 37
= 20 + 37
= 57
F = 57 °F

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.
