To describe violent storms, such as hurricanes and tornadoes, meteorlogists use the formula D^3 = 830 t^2, where D is the diameter (in km) of the storm and t is the time (in h) that the storm is expected to last.
If a storm has a diameter of 25 km, how long is it expected to last?
Thankyou for answering this question! The last of all of my difficult ones. This most likely would have been easier if I was 2 decades younger! Thankyou for your help.

D^3 = 830t^2
25^3 =830t^2
15,625= 830t^2
t^2 = 15,625/830 = 18.8253
t = 4.34 hours

25 cubed= 15625
15,625/830= 18.825301
The square root of 18.825301= 4.34
Therefore according to that formula the storm would last 4 hours and approximately 20 minutes.
