Answer:
2727
Step-by-step explanation:
The formula for finding the volume of a cone is
1/3πr²h
The radius would be 11.5 because, radius equals the diameter divided by two.
So, first you would plug your numbers into the equation
1/3(π)(11.5)²(19.7)
*use 3.14 for pi
Then multiply.
V = 2726.9 (2727 if you round to the nearest whole number)
The wale school has the lower student teacher ratio
5b+4+10=-2
5b+14=-2
5b+14-14=-2-14 1) subtract 14 from both sides
5b=-16
5b/5=-16/5 2) divide by 5 on both sides
b=3 & 1/5
