William has clearly not studied. 

There are five choices for eight questions. The probability of getting a question right is 1 in 5 or 20%. The probability of getting all of them right is 0.00000256. The probability of him 6 or fewer questions correct is over 99% likely.

A cone has a height 25 ft and a radius of 7 ft. Is a reasonable that the volume of this cone is 100 ft3? Why or why not?​
Nostrana [21]

Answer:

No

Step-by-step explanation:

the radius squared is 49 times π, which is roughly 3 means the area of the base is roughly 150 ft².

This means that one third of the height cannot be more than 100 / 150 = 2/3 of a foot. That makes the height about 2 ft, much less than the reported 25 ft.
