Answer:
17 days and a half.
Step-by-step explanation:
First, we can find how much money he makes per day cutting lawns. This can be found with the equation:
40 x 5 = 200
He makes $200 a day cutting lawns.
Now we can divide his goal money ($3500) by his daily rate ($200) to get the number of days it will take to reach his goal.
3500 ÷ 200 = 17.5
It will take him 17.5 days to reach his goal.
Answer:
Let S be the total surface area. Then
h = ( S - 2 Pi r^2) / ( 2 Pi r)
Discussion:
Let S be the total surface area. Then
S = 2Pi r*h + 2 Pi r^2 => subtract 2 PI r^2 from both sides
S - 2 PI r^22 = 2 PI r*h => divide both sides by 2 PI r
h = ( S - 2 Pi r^2) / ( 2 Pi r)
