Surface area = πr(r + l)
500π = 15π(15 + l)
100 = 3(15 + l)
100=45+3l
100-45=3l
55=3l
l=55/3
l=18.3ft to one decimal place
Answer:
Step-by-step explanation:
For missing hypotenuse: 
Plug in the side lengths that are known to find the hypotenuse.
1. No, the angle is less than 18 degrees (closer to 15), so it is not safe
2. The length rounded to the nearest tenth is approximately 15.5 feet.

--------------27------------
JK + KL = JL
6r + 3r = 27
9r = 27
r = 27/9
r = 3 <=====
Answer: 32 tents
Step-by-step explanation: 250÷ 8= 31.25 so you have to round that tent up because you can't just have a quarter of a tent. So 5 makes the 2 go up and it becomes 32
Answer:
convert the expression for N into logs
evaluate those logs using a log table
thus determine log N
calculate antilog of log N
Thus,
